We do a family reunion with my immediate family every year and this year, we went camping at the end of July.  We ended up going to a place called Smith and Morehouse for a few days this year.  We  had a lot of fun.  There were projects for the kids to do and we took them fishing and hiking. 
Mostly, all the cousins just loved running around together all day long.  The kids got pretty dirty, especially because it rained a couple times.  Luckily, we had an extra tarp and Steve set it up for some great shelter.  And luckily, it didn't last long when it did rain.  On of the afternoons was so hot that we stripped the babies to just their diapers because they were sweating so bad.  I  had to take a couple pictures of Conley and Eliza (one month younger) sharing a pack n' play in just their diapers.  We played games and visited and this year, Steve and I dutch-ovened for the meal we were in charge of.  We had to do dinner - thanks, Brian (not).  We ended up using six dutch ovens for dinner and a huge 16" one for dessert.  Our group is pretty big :)  The kids did pretty well with camping.  Brinton especially stays in his sleeping bag and just sleeps all night.  I think Zander woke up early one time and ended up sleeping next to me just so he didn't go out of the tent to play.  I am always surprised at how well the kids can do camping and we had a lot of fun!
