Both are nice! Depends on the occasion. If you just finished school and the summer came, go out to the wild with your buddies! a few days out there, singing, dancing, drinking around the camp fire would sure make a great celebration and memory!
Or better, go camping with both your family and your buddies! invite your best bud's family too so things can get more entertaining as both of your families share the things that you don't know about each other!
