I try to go every Sat morning when up to it. I go online to Craigslist, local newspapers, Pennysaver and other sources to get the addresses. I then use Garmin Mapsource and Mobile PC with my laptop to prepare the shortest route and the off I go letting Garmin do all of the navigating. I tell my doctors I do "hear voices" and just try and do what they tell me to! I pick up a lot of bargains for example a nice coleman 2 burner gas stove for a buck, a lifetime supply of lanterns for about 3 bucks each, tools and all sorts of useful stuff. Garage saleing is one of the best kept secrets for saving some real money and buying things you couldn't justify ordinarily.
Try it, you'll like it.
Cheers,
Gus
