So while I figure this will be of fairly limited interest, thought I'd give ya'll a shot before I donate them or pitch them. I have 11 vintage USGS topo maps of the Northern Idaho and Eastern Washington area that might be of interest to someone who's an avid camper, hiker, etc. They date from the early to mid '70s, but the topology hasn't changed in that area to my knowledge. So if they would be of use or interest to you, here's your chance for some great maps at the 'right price'.
Pick a number between 1 & 50, between now and April 1st. I'll draw numbers, or try one of those random generator thingies, and ship them to you via USPS Media Mail. I used a few of the Idaho ones back in the day when I was still camping, and it's hard to beat their detailed information. Good luck.
