Like I said in the last post been parked in my sister's driveway for a family visit and reunion and today we sister, brother in law and nephew went for a ride on the Three Rivers Heritage Trail in Pgh. PA.  We started across the Monongahela river from South Side crossed the Hot Metal Bridge which used to be used to carry iron from Eliza Furnaces to the South Side past the practice fields for the Pgh. Steelers and Pit Panthers to Eliza furnace and pump house which today had an art fair with a local winery having a wine tasting.  Of course we tasted. Then continued Southeast past Kennywood Amusement park along the river and crossing bridges to where we had to turn around due to time restraint.  This trail is part of the GAP or Great Allegheny Passage from Pittsburgh to Wsahington DC.  Eventually it'll begin at Greater Pgh. Int. Airport through the South Hills to Pgh. and on to DC. Imagine flying into Pgh. or DC with a bike and doing this trail for 300 some miles one way then flying home.  Most of the sections we rode today were paved and well marked with lots to look at. Had lunch at Mitchell's Fish Market, yum, cedar plank salmon.  Will do this trail further next week.
