We took the kids to Pitsburgh for the day and made them do a ton of walking. Word of caution is to never take young kids to a city during a drinking holiday (St. Patricks Day). If you do I will bet they will get a ear full of drunken trash mouth and this was on the main streets, we need to keep these people contained to bars then more families will come to visit the city.
Other then that we had a great day, a little cold on Mt. Washington when we were taking pictures.
