Lots of the RMs will mail you the map if you mail them a check first. Most are small offices run by a couple nice ladies. Give them a call and talk to them. Practice for all the calling you ll make when there. When you do make calls and get permission, always ask if any of their neighbors friends "need help getting rid of birds". If , ask them to call them for you, much easier than a stranger calling to get permission. Lots of super nice folks willing to help you out, great people like it used to be here. Good luck up there. Hope this helps.
