what they are telling you sounds frustrating - but it's right. the only thing that matters is what you can do with the first-aid gear. Otherwise having it there is of little use. So it boils down to training and experience. you can pack your own from any local pharmacy - if ou know what you want.

your best bet is to get a few basic items and don't go overboard for your first trip. chances are that you won't see much more than a sprained ankle and some sunburn - or chapped lips (OK maybe not sunburn at this time of year). you need to start taking some first-aid classes. skip the Red Cross classes ... they don't teach the real stuff any more.

good luck,
