Long before GPS in our phones provided direction and Google Maps provided illustrations, the Dell Mapback series of paperback books ruled the racks. If you would like an affordable hobby (especially if you aren't too fussy about condition) these colorful and downright cool paperback books with "scene of the crime" on the reverse are perfect. Graphic and lovely. I've put together groups of them all my life, then parted with them and started over. Many antique malls have a few. I will generally go 5 bucks each. There are, I believe, some 500 of them. Westerns, Romance, Murder and more, all with cute little "X marks the spot" maps.
