We had noticed that a storm front was coming in.  Unfortunately it hit just as we were getting back to camp.  Unfortunately we were NOT prepared for it.  Many Scouts had gear sitting outside their tents, or the doors to the tents open, or not staked out, or something like that.  (Remember we were all in a hurry to go swimming).  Thankfully the rain didn't last long, but a bunch of stuff did get wet.  This is a picture of the moon as the storm was breaking up.
