| You are welcome to use my GPS if you like. it is a handheld Garmin eTrex Vista. Top of the line in the handhelds. If you have a laptop you can interface it with that as well. I've used it for trips and such and found that it's quite accurate. (Garmin says it's velocity is accurate to within 0.5 meter/sec steady state) here is the site: [ http://www.garmin.com/products/etrexVista/ ] It also provides some measure of data logging for your speed, altitude, etc... I'm in the DFW area so if you decide you'd like to use it zap me an email and we'll arrange a meet. Good luck!
