Russo,
I retired a year ago yesterday, almost immediately took off for an extended trip to Florida, got back and then was gone again to NV, got back and them whamo. Covid took over the world and the fun kinda ended. Spent a good bit of the Spring holed up like many. We had big plans for summer which got completely reset. We still got out and did some things but nothing like we'd planned and, of course, most RR activity was severely limited. Now we're headed into winter and everything's shutting down again so yeah... a bit more time - for a bit.
NN #40 is, indeed, a beauty. Unfortunate that you missed her when you were last there, and now she's down again. Her boiler time is up and she also is apparently overdue for some running gear work, so the NN folks believe it'll be about 2 years before she's back on the rails. The good news is they're getting close to finishing the restoration of 2-8-0 #81 and should have it running in 2021 so they'll still have two active steamers.
