Recently I was looking for a new (to me) sailboat and Craigslist was an obvious site to visit. Living in Charleston, SC I visited the local Craigslist often but soon realized that I needed to expand my search.
The natural path is to bookmark Craigslist sites for Myrtle Beach, Charleston, Columbia, Hilton Head, and so forth then surf to each site daily while the babies cry, the spouses stew, and the dinner burns.
Wouldn't be great to visit one location where you could see all of the boat listings from half a dozen cities?
