Ten good lessons.
I could add one more - fill the truck bed with tanks in the morning and don't come back until late.
Yup, here's a picture of me (taken by tajkd) sleeping on 8 of the 10 tanks in the back of our truck during our surface interval at the Hilma Hooker...
This shot was taken early afternoon. We left Plaza Resort after breakfast at 7am, and didn't get back there until after dinner and drinks at Papaya Moon. Did five dives that day.
The need for a "truck full of tanks" is important if you are doing up north, because once you hit the one-way portion of the road, it's a L-O-N-G way back to your resport/shop to get fresh ones. Even more specifically important to bring at least three tanks each to the park, since you'll be investing 1/2 - 2/3rd of a day on the drive itself.
