Sleepygeek, thanks for the update on your childhood in the 'burg. I grew up in Munhall, lived in and out of the city, and now live in the North Hills. My Uncle lived right behind the old St. Francis Hospital in a duplex.
Things have changed a lot in Lawrenceville, it is now the up and coming part of the city. Putting in Condos where the Arsenal used to be (and finding old shells while digging), tore down St. Francis and built a new Children's Hospital, and moved St. Margaret's to the Water Works in the Aspinwall area.
Good luck with your RV and safe travels.
