Tour de Vermillion with my Garmin 301

I had an hour to kill before going to the USD Women's Basketball game so I decided to do a "tour de Vermillion" on my mountain bike. I also wanted to try to put my Garmin to the test by not constantly going in a straight line. Well, it did "okay" but I wouldn't say it did a great job. There are a couple points where it looks like I drove over a church and a couple houses. I still love it as it seems to be real accurate with total mileage ridden, but I wish that it was more accurate on the mapping side of life!
