(CV4W - http://www.cv4w.org/) by Scotch
A new feature for the Calendar of Events section: Trail Heads Map!
You can see it from the Calendar page, the Site Map, or this direct link: http://www.cv4w.org/events/trailheads
It maps out the trail heads of every event (that has the required information). You can see all events (past and present), or just upcoming events.
Clicking on the Map "Pin" will display the title of the Event (which is clickable to go direct to its details page) as well as the month/year of that event.
