It's a gorgeous day out today so I thought I'd take my geo-pony out for a ride and grab a cache that I've been wanting to get for a long time. Hauled out to the area, saddled my horse, and.....can't get any satellites. Now, I've had this problem on cloudy days and in the woods but I was in the middle of nowhere (no tall buildings), in a desert (no trees), on a gorgeous cloudless day. I couldn't even get one satellite to come in with even a weak signal. Any ideas? I use a Garmin GPS Map60. Last time I used it was about a month ago and everything worked fine.
