There isn't any parking close to the pier, angry rangers in flashy golfcarts will run you off and threaten tickets. Lest you park across the highway in the park itself and make the walk - its quite a way though. I would say further than the walk to Destin Jetties.
I still don't know where I"m working tomorrow, didn't get back to work in time this evening before the doors were closed - ugh. I'd probably be up for a dive around 6-6:30ish.
Probably diving the beach sometime this weekend, but not the jetties, and not the Whiskey...
