thanks AZBuck,

as for camping, I've looked at some campsites that have websites, and the price seems to be about 30-40 per night. however, on the forums, i see people quoting prices as low as 10 per night. i suppose these are less developed sites that don't have an online presence. i was wondering how well advertised these are on highways, and if not well advertised, how do we find these cheaper places?
