A realtor can help, but you might want to check with Mike for what is
currently available and how the site location can affect building time, resale
value, and some of those little "secrets" that only come with experience!
In this day and age, the Internet is the best bet.
www.calaverascounty.com would be a good start.
Of course, you can't beat a personal visit to the area. You just can't get that
smell and feel of the mountains and big trees on the Internet!
