ok, this is the best. prevent playa foot...take the cooler water out of your cooler and put it in a big bucket or tub. add some vinegar to it. take off your socks and shoes, and put your feet in there. beware of brain freeze! best done in heat of day...repeat as needed, usually at least once a day. if you can get someone to mist you and bring you cut up fruit while you're doing it then you is living large :) fun to share.
dry nasals - there is this stuff called Ayr and it is an aloe and saline gel. you put it up your nose. I know, it sounds gross, but it is the best ever. ever ever. try it...you will like it. nasal rinses are good, but this is better.
feel like you got baby wipe and sunscreen all over your face, and need to start over? use a mister or spray bottle to wet your face down good (very nice first thing in the morning), and wipe it with a towel. good stuff.
now here is a question for you: by the end of the event, last day or so, a weird thing happens around my eyes. there is this area that is inside the goggles, under and around my eyes. it gets all wet and sweaty and soft, all the sunscreen goes away I guess, and then it gets exposed to the air and wind when I switch to sunglasses later. yikes! alligator face. what to do?
just listen to the drum
