For those of you who are a little internet impaired.
The easiest way to find things on CL is just go to google and type what you want to find, i.e. panhead chopper and then put site:craigslist.org. Putting the site:craigslist.org will pull all the ads from all the craigslist's instead of having to go through the cities individually. Doing that will pull up all the listings, even expired ones, so its best to search for "from the last week" in the options menu when you do your search.
