Greg, if you relocate to Spokane there are several lakes w/in 30 mile's or so. Ryan mentioned a few really good places to ride, but there are also a few smaller lakes like Long Lake, Liberty Lake, Newman Lake, the Spokane River and so on that are a little closer to Spokane. The smaller lakes are great for mid week riding. A typical season would be April and May you'll want a drysuit/wetsuit. June through September it's summer and warm. October wetsuit/drysuit depending on how cold you like to be.
Good luck w/ the move!
