For my birthday we spent the weekend in some campground cabins with some cousins.  It's in the middle of a 7.5 mile trail.  We rode bikes to one end and back in the morning.  We rode to the other end and back in the afternoon.  That's 14 miles.  The  boy loved it.  Also, he has a new love.  I bought a little kite when I bought groceries.  I showed him how to run with it in a straight line so it flies high behind him.   He was running around with that kite non-stop for two days.  He seems to like it better than a helium balloon.  I didn't think that was possible.  :)
