OK, this is a bit confusing. There is a place called Thunder Lake Cabins operating as of 2022. It is on Ramsdam Rd. The place on the post card is Ramsdem's. Maybe the post card company mis-printed the name? I think they are the same place and the remodeled cabins look amazing. There is also a place called "Whispering Pines" down the road on Thunder Lake that also has cabins so is that the new version of this place? Or neither? I'll keep digging.
