Boat Camping - 3 worst mistakes

I can't stop at just three.  Please do not ask why I am so acutely tuned to these errors (especially the last one -- arrrgh!).

0. Failing to pitch your tent above the midnight high tide mark if not sleeping on boat.

1. Failing to have enough dry bags to keep your gear dry.

2. Failing to run your food up high enough (and far enough from the tree trunk) that the critters (rats, raccoons, bears, etc.) won't get into it if you're staying ashore for the night.  Or not packing it securely so everything is a mess once the boat stops.

3. Failing to bring enough fuel for cooking.  There are no propane filling stations on the water.

4. Failing to bring enough drinking water (or, forgetting the filter needed to produce safe water from surface sources).

5. Forgetting the TP and plastic bags to store waste securely.

6. Leaving the sleeping bag, pillow, stove, food, etc.) home.

7. And the worst:  leaving your sense of humor at home.
