Hey guys!
FYI, Bonanza happens in Nevada. The Ponderosa Ranch is just East of Incline Village, NV. It is at Tahoe, though. Also, the Comstock Lode happened in Virginia CIty, NV, which is where the Carwrights go when they talk about "going into town" or whatever--which is funny, because it would be a couple of days ride by horse from the Ponderosa to VC.
Also, the Donner Party traveled 12 miles north of Tahoe, on what is now I-80, through Truckee. There is a serious mountain range in between,
Love the show, just trying to help out!
