First thing that came to my mind when you said where you are and when you're doing is was camping...definitely can be a great bonding experience for everyone! Might want to check with local parks etc. about that. For one of our house retreats, we went to a local park that had a low ropes course, so we split off into groups to complete that...surprisingly fun and good bonding as well. Basic thing to keep in mind is to do something everyone can do together or at least in decent-sized groups (avoiding separations into cliques/small groups as much as possible). If you do participate in an activity that requires groups, make sure they're not too small, and try to put people in groups that don't normally hang out a ton, it's always nice to get to know everyone better. Another good idea is a volunteer day...contact a children's center, shelter, YMCA, humane society, etc. and talk to whoever's in charge about bringing the whole group down to do some good deeds. Everyone will have fun doing it and feel really good about themselves at the end of the day! (Plus you get your community service hours done
) Hope this helps!! Keep us posted on what you end up doing and have fun!
