I'm always on the lookout for interesting GPS trails to experience through Google Earth in my StarTraX GPS animation program (download FREE to your PC from http://www.gpsanimator.com)
I would really like an improved searching facility on the GPS Traces page - it's limited to searching by tags, not all of which are very complete. It would be great if you could provide a search by proximity to a co-ordinate - eg to find trails containing points say within 10 miles of a user-entered co-ordinate?
