I just started planning a road trip from MN, to OR, down to CA, and back. I intend to check out vineyards, the Coors brewery, Red Rocks, Anheiser Busch, and anything else I have time for. I have about 3 weeks-month. Can anyone offer any suggestions/tips for something like this. I will be traveling alone, and staying w/ friends along the way, so lodging isn't a factor.
