The speculation of whether or not Garmin is launching a cache listing site of its own is over. According to Christian Gallus the editor of Geocaching-Magazin, on November 8th the opencaching.com website was available to the world for approximately three hours. Recognizing that the site was from Garmin Gallus grabbed the screenshot you see here.
I found out about the opencaching.com screen capture from the publisher of the Dutch blog www.gps-info.nl who is a regular reader of my blog. Thank you Guido.
