At each of the stops on our Colorado/Wherigo road trip, we've made the same plea for feedback on the Colorado. Tell us what you like, tell us what needs work, and we'll do our best to make a great product even better. Just released this week, this free, downloadable software update is a perfect example because it: 1. Displays caches on the map. 2. Double the numbers of caches - to 2000! 3. Adds the ability to log caches as found. 4. Provides support for Colorado Field Notes, which allows you to auto-generate logged caches by sending a file from the Colorado to geocaching.com.

And don't forget that buying and registering a Colorado gives you access to a free trial premium membership to Groundspeak's geocaching and Wherigo sites. To learn more about the Colorado and Wherigo, join us on Saturday at the Garmin store at 663 N. Michigan Avenue in Chicago. Sessions begin at 10 a.m., 1 p.m. and 3 p.m. I'll be there with limited-edition geocoins!
