Great Site about all you want to know about Garmin Watches and GPS
My Garmin Forerunner is starting to act up and I'm researching what I would like to replace it. (The 610 is the winner). In the process of researching it, I found a really cool site where DC Rainmaker has done reviews on Garmins and other watches, has Garmin tips and talks about the accuracy or inaccuracy of GPS. Not only is he techy, but he's also an accomplished tri-athlete and will soon be in the Men's Health magazine. You should spend some time on his site checking out all the cool stuff. Here are the links relating to Garmin and GPS that I found interesting.
