Preschool ending/ Zoo fieldtrip

Preston was in a kind of coop preschool this past year.  A bunch of Mom's got together and took turns taking the kids every week for a couple hours Tues. and Thurs.  We had an end of the year field trip to the zoo.  It ended up pouring rain on us by the end and we were all soaked, but we were able to see most of the exhibits without too much rain in the beginning!  The kids thought the monkeys stunk and all plugged their noses.  I agreed!  This tiger kept standing on it's back paws and pawing at the glass where all the kids were standing.  Apparently it does it quite often (or so we were told) and is it's way of saying hi.  The kids were all scared at first but loved it and thought it was hilarious after the initial shock of a big lion scratching at them was over.
