Too Hot waiting for this tour to start. Don't take this tour if it's hot or cold. Maybe the tour will be okay. Uhm.. The tour .... Full of corny jokes, ( that's okay) but over the head of most of the kids. Not much about the history of Pittsburgh or architecture. Spent 20 minutes or more in the middle of the river watching kids drive the boat and very little informative dialogue. Maybe this tour is best left for kids or? Sorry, tour is not great for 25 bucks a piece. Better to hire a guide and tour downtown etc.
