I just got a Garmin 205 GPS and am anxious to use it on all the local mt bike trails. Currently I only have a portion of the Johnson Branch trail marked. The wrist watch GPS so far has worked flawlessly. No problems with loosing satellite connection. Need to get a helmet cam next to integrate video into the TxTracks.com site. There are many options out there. I am leaning towards a sony CCD version and a SD card video recorder. Hopefully the trails will dry up soon so I can capture some good data & footage!
