I love Kate Sessions Park.  We use to take our daughter there all the time when she was little.  Her preschool was right up the street so sometimes we would go there to play.  But that was about 5 years ago.  I have recently discover Kate Session Park as a really cool place to go for a hike.  We took the Girl Scout troop there the other day and it was awesome.  Hope to go hiking with the hubby there soon!
