I fail geography

A long time ago, I used to be fairly good at geography. I knew most of the countries and states on sight. However, I just recently found a little SVG game by one of the really cool short game writers and realized that I was wrong 94% of the time. The states I did better, about 1 in 4. I need to get a refresher on those, I suspect. Maybe this is one of those things using loci methods of memorization would be useful? Na. :)
