Tim I love the enthusiasm! That sounds awesome. I thought we could start by just simply cutting shorter legs for 1 table and going from there. Once we get people on the ‘Pittsburgh topography’ bandwagon, we can expand our horizons. I think the first step would be to take 2 minutes to cut shorter legs of 1 table and look at how we begin to fill that in with pieces.
I like the table skirting idea. Personally, I think those clamps are wonderful yet kind of a burden to haul around and time consuming to set up. My ideal solution would be to build a 40” track section to attach to 1 edge of every table. The sneeze guard could ride in this track and the Velcro could be screwed/stapled to the outside of it.
