Welcome to the forum Kyle. Lots of guys like old iron on here. One rule here is that there are no craigslists post allowed but we can still point you in the right direction.
Exactly where are you?
What do you guys use them for?
We like Pictures!
There is also one in northern MN, carr lake and south of twin cities but likely shows up in twin cities search. An aggregation tool called searchcraigslist.org crawls craigslist but is not perfect but searchs all of the US.
craigslist itself allows you to search within 200 miles of any zip code and by picking 5-8 zipcodes carefully you can pretty quickly scan a big chunk of the USA, just about as much as you want to drive to I think. That said, in Canada there is another site used much more frequently, maybe a Canadian poster could jump in on that.
