Your first response may be "any idiot should know that!" but please bear with me ...

1. What type of clothing is appropriate for the Texas Hill Country this week if the forecast is calling for daytime highs in the upper 60s and nighttime lows in the upper 40s? My 16yo son and I are going to do a test hike overnight at Enchanted Rock to try out all our new Christmas toys. Neither of us probably have appropriate clothing as he wears a uniform to school and doesn't have many casual clothes at all (nor do I). Since we have to buy some clothing anyway, I'd like to buy what is most appropriate. I cannot tolerate being cold; he's fine with it.

2. What about changes of clothes? Different outfit for every day? Do you sleep in what you wear during the day?

3 What about personal hygiene, specifically caring for oily teenage skin?

Thanks!
