If you haven't already, make sure to check out EveryTrail.com, the GPS Travel Community!
We launched 4 months ago and an active community of global travelers is emerging. Users are sharing all kinds of trips, from sailing in Greece, to driving through Namibia in a 4x4, to scooter trips in Hawaii and hundreds more trips!
One cool way to share your latest trip is to embed a FULLY INTERACTIVE trip map into your own blog. For example, take a look at this flight above San Francisco and Silicon Valley.
