Beat the high cost of Hops. Grow your own!

Here's a link to a place where you can order Hop rhizomes in many varieties. And it looks like ordering opens up March 20, 2008. I don't have any financial interest in this place, nor have I ever purchased anything from them before--it's just something that I found after doing some research.

I suspect that Hop will grow here where I am in NEPA as my father told me that some grew wild behind the farmhouse where he grew up. Further, I read somewhere that up-state New York was a huge producer of Hop at one time (1800s) before the industry moved out west.

Has anyone grown them successfully in NEPA and can you give some gotcha pointers?
