We've added a link to the Search for Rides page to search for brevets and other events, and perms within a radius:

Search for brevets on a map (created and supported by Jake Kassen)   

This tool has a lot of features. It displays nearby brevets (using some heuristics, including the route assigned to it or the locus of the region), and permanents, plus when routes were last used. You give it a location and radius to search - e.g., "rides within 80 miles of Frisco, CO."

The existing ways to look up rides or regions are still there:

• one or more regions' events
• one or more states through which brevets with assigned routes pass
• Map of regions - a quick way to see where regions are based

Thanks to Jake for developing this useful tool!
