Tahoe has 4 sick courses, and they're adding another later this year (in addition to one in nearby Reno), it really should be a mecca for disc golf. The entire area is set up for tourism, it would be easy for them to host a national event there, and with the courses (and other fun activities) they have I don't think Worlds is out of the question.
Talked with the guy who designed and maintains the courses up there last weekend and he said that the reason disc golf hasn't exploded up there is because the community is kinda weak, plus there's so much other stuff to do up there. But I see an impending explosion of interest coming on. I will rep this place as long as I'm out here, hopefully it will get some more recognition.
