There is a culture, much as I am on a diet.
Do not misunderstand what I am writing: Roatan is a lovely place to do a dive vacation. Know this (or not):
The island is English. The ruling class is English. These people all have cousins in Cayman. True. The "Spaniards" come from the mainland. Some are like guest workers, most are blamed for all the crime. At least the crime where people get hurt, versus where people get ripped off in business (The English have that franchise). The Blacks are the Garifuna who were dumped around the Caribbean after their masters grew tired of their strength and self reliance.
The government of Honduras (the country) is Spanish. In language, culture, heritage and people. They come to the Bay Islands to help out. (Like when Roatan Airport couldn't pay to keep their lights and a/c on even though they sent the $25 fees you paid to Tegucigalpa on the mainland. Do the math.)
The music is island reggae pop rap noise. You can't hear a Central American flute to save your life. The Garifuna put on a folklorico for the cruise ships. You can see them eeking out their existence in Punta Gorda- nothing traditional. The LDS school also does a mainland Honduras Spanish folklorico with the kids.
It pains me to say, that the island culture is horribly racist and sexist. I have indeed spent considerable time in Honduras, largely in the Bay Islands, with substantial time spent in service to the local govt as well as several and various NGO's. I know the drill fairly well, at least from my biased perspective.
This should have no real impact on the visitor, because, yes, you will be happily insulated from the reality of the pecking order (see above).
Honduras was created at the behest of the United Fruit Company. They are the USA guys who marketed bananas then pineapples to the US citizens- quite the novelty they were at the time. "We" (at their monetary urging) sent our boys and engineers down to Honduras to kick some butt and build railroad tracks. These tracks and transport hubs did absolutely no good for the population, nor any commercial interest other than United Fruit.
When you walk into Banana Republic, know that Honduras was the banana republic. The one, the only.
During WW2, we garnered cheap manpower to staff the merchant marine. Seen the monuments and plaques at cayman and Bay Islands for the lost seamen? As the war ended and the men stayed on, sending home their comparatively large checks to "mom", they priced themselves out of the merchant marine market. Our shipping fat cats looked to new impoverished islands where the boys came cheaply. (The northen coast of South America became a recruiting ground)
When you tell people that you're going to Honduras, they immediately say "what about the war?" You and I know that ended twenty years ago, but to distance itself, the islands rarely use the name Honduras... they went to great lengths to teach people the correct way to say it.... "Raaaah-ah-tahn" ... Well, the "English" way to say it.
The war was hundreds of miles south, over a mountain range. Once again, like United Fruit, we came in and used her and paid her and left her... again.
Then Red Lobster discovered the place. Then after overfishing they dumped her.
We have poured so much money into this country, then withheld it... it is a product of our torment. How you gonna keep 'em down on the farm once they've seen MTV? And see it, they do- everyone knows where the nearest sat tv is located. There is a stream of people legally moving North and in with their Aunts in Tampa. (Little Honduras)
Much as Chicago benefited architecturaly from being burned down atthe advent of glass/steel skyscraper tech- the Bay Islands have become instantly connected by cell phones. The technology changed the place overnight, more than the paved roads and military surplus construction gear they got after the Nicuraguan war.
You can find the most interesting, fascinating, loving people on the planet. It is not hard. Many of them are your DM's (who rate pretty high on the local socio-economic scale!). But to say that there is a representative island culture- that is just no longer the case. It is an odd melange of pop-gangsta-afro-rasta wannabe... even for the Latins. If that's what passes for a "culture", I aint seeing it, other than in a stricly academic sense.
Quick, go to Utila. I give it 2 years if the present economy keeps up.
But then again, what do I know. I just sit my pasty white @ss on the barstool at my secluded AI resort and drink diet cokes. See... I am on a diet!
