A while back, I suggested that a fund-raising event could perhaps be held right there at Strasburg--a chance to see RGS #20 before she gets shipped back to Colorado. Something like a full-day shop tour, with a "lecture" first, including lots of Lynn's photos and a detailed description of all the work done, and then a close examination of the locomotive. Lots of Q&A, hands-on inspection, photo ops.
But who knows how many NGDFers and RGS fans are geographically close enough to make it worthwhile. The actual amount of money raised might be pretty modest, when all is said and done.
