Many years ago, probably around 1970, Colleen and I had the brilliant idea to take Alan and my brother Ernie to Frick Park.  We set out walking from home and it was a beautiful, warm day.  We got to the top of the park on Braddock Ave and decided to walk the trail to the bottom.  We got to the bottom of the park and went through the soccer fields to the stream.  The boys played in the stream for a bit and everyone decided it was time to head home.  Some how we got turned around and followed the creek in the wrong direction and ended up at the bottom of Commercial Ave.  When we finally realized where we were and that we had a bit of a walk to get home, both Alan and Ernie threw themself on the ground, flat on their backs and refused to move swearing that they could not move another foot.  Eventually they got up but not after a good bit of grouching and complaining.  It ended up being a great day for all!
