As is too often the case, I stumbled across a site today that I found...interesting. Thought I would share it here: 200 miles from Tucson (withinhours.com) put in a location and the site will show locations of note up to 200 miles distant. This falls into the oft discussed 'Golden Horde' and '300 miles on a tank of gas' planning stuff. Posted mostly for your amusement.
The site works for destinations outside of the USA, so should the apocalypse occur whilst on pilgrimage to Rome, Mecca, or or Jerusalem, one can identify where all the lootable places are between there and home.
