Having missed out on the MTH sets, I was thinking of getting the 1990's scheme. I presume it includes these sets:
2227030 looks to be #62 Gobblers Knob and #59 Grasshopper Level(1990's)
2227040 looks to be #72 Mill Creek and #70 Cherry Crest(1990's).
2227170 looks to be #60 Eshelman Run(was this renamed to Donald E. L. Hallock) and #96 William McFarlan(1990's).
I have to decide if I should spend that kind of money, or just keep hunting for an MTH set.
