GPS tracks for trips... good website?

I know a number of others out there are carrying GPS devices with them... I was curious if anyone is posting their GPS tracks for their trips? If so what sites are you using? I have found the following sites good for posting various adventures:

www.motionbased.com
connect.garmin.com/

It would be great to have a repository of these GPS tracks to show all the areas that people are skiing...

One that I discovered recently is this:

www.everytrail.com/

Despite the name, it doesn't offer a whole lot up here at the moment. It offers GPS data as a Google KML file as well as a GPX file for your GPS unit.
