Remember to drink water before going to bed.  A couple nights I didn’t and woke up with a very dry, uncomfortable mouth.

Bring more costumes!  Also, more playa-wear.  Even jean shorts without a shirt felt a bit pedestrian at times.  The loincloth worked well.  Sarongs?

Go shirtless earlier in the week.  My forearms tanned more rapidly than my back and shoulders, meaning that I had to deal with sunscreen over a longer period of time.

Either get sunglasses or a pair of goggles that fit my face better.  I don’t normally wear sunglasses, but the sun on the playa was bright.

Bring more food.  Most sites said I’d eat less than normal when I went out there.  I ate more.  (Probably as a result of being very active and walking a lot.)

Relatedly, peanut butter and jelly sandwiches are simple to make and reasonably non-perishable.  Would make good lunches.  I should still bring power bars for portable lunches away from camp.

Cereal is good for breakfast, though I don’t like eating it dry.  UHT milk needs to be referigerated after opening.  Does Rice Dream?

Get a bike.  I liked walking everywhere, and I walked a lot, but bikes are a faster means of going places.
