Wow, I ahead of the curve again. We've got all sorts of maps. Some we've been given, some we've bought and others we've traded for. I seem to like the prewar maps the best. My current favorite is a 1926 Colorado map. Its titled "Blazed Trails of Colorado" and then 1926. I've always considered posing the map alongside a model 1926 44. Oh, and probably a Heiser holster of similar vintage. I don't think I've got any great knives from that era. We've knocked around Colorado enough over the last 30 or so years that we've grown kind of familiar with some places. The 1926 map is good because the towns they show are currently regarded as ghost towns today. Same for railroad stops.
I've also got one from Wyoming of the same vintage. We haunt antique shows and its not too uncommon to find someone selling older maps. I've not seen anyone foolish enough to ask $150 for them. I had a great old map that showed railroads and even canals, but no roads in some places. I think I gave that to my brother, a railroad nut.
I've got a local city directory. Not phone, but occupation. Its got everyone of consequence along with their occupation. In the front its got a tissue paper map of this area with the streets and lots marked out. Of course almost all of the stuff has changed, including roads. I live on the river. I'm on the highside, but there's little between the other side guard rail and the water. But the old maps correctly show this property as being up on 2nd street. Front street is now submerged due to higher water levels and dam construction.
In just the few short years, google earth and mapquest have moved to newer pictures. These have been taken with foilage on the trees. The old ones, say 8 or 10 years back were winter aerial photos. Up on the hill behind me I could see some foundations on those. They pretty well correspond to where roads were 100+ years ago. Current streets don't follow that same pattern or spacing. Guess I've gotta go upstairs and assemble the old maps for reviewing. Well, that or sales to someone foolish enough to pay me big bucks for them.
