Welcome to the forum, Longbows. You've gotten a start here with very sound advice. It's really important to keep your ducks lined up as you proceed.

As an aside, I lived for many years(13) down the road from you. Lloyd Lane on the Snake just a mile above the Marsing bridge. My 7 acres was immediately adjacent to a gravel pit. I wanted a pond, but without big bucks for a liner, I wasn't going to keep water in my porous soil. I did have 345 feet of Snake River frontage, so that was some compensation. Ha!
