The Al Dente blog wonders if there will be a pumpkin panic in 2010. Not around here, I'd say.
In Fishersville, one of the churches has a pumpkin stand set up - raising money for Haiti. Another stand is set up in Staunton, near the Frontier Culture Museum (and the Starbucks Smitty visited). We bought from there last Halloween, when the oldest decided Halloween morning to get a pumpkin. There were only a few left, but we got two for carving.
SWACgirl noted the pumpkin festival in Churchville. If you can't make it this weekend, there's always next weekend.
If you need pumpkins, Augusta County is the place to be.
