Crazy? Nah. I just got in to homebrewing as well, and in fact I planted some hops yesterday in my backyard - just in time for winter! THAT is crazy.
What I'm hoping is they will get some growth for the next month or so, go dormant in the winter, and then will have a bit of a head start for next spring, being already in the ground and all. I planted them in terrible dirt, and am just really hoping for the best. They are inexpensive so I don't care if I have to start over next spring.
