- Don’t add waypoints before leaving home
- Enter coordinates by hand instead of transferring them from a computer
- Don’t bring along spare batteries
- Don’t bring a map and compass as backup
- Don’t mark your trailhead before hitting the trail

Free topos and aerial photos: USAPhotoMaps Everybody loves stuff they can get for free, right? Especially if it is way cool and quite useful. Well, USAPhotoMaps fits the bill. Created by Doug Cox, USAPhotoMaps is TerraServer-based, just like TopoFusion. And just like TopoFusion, you can look at aerial photos or topo maps of just about any location in the U.S. For some urban areas, you can even view color aerial photos down to 0.25 meters/pixel (see below left)! One of the ways I've used USAPhotoMaps is to locate newer 4WD roads that don't appear on topo maps, which are usually much older than USGS aerial photos. In the image on the right below, I've drawn a track along a logging road. To the left below, you can see how I've been able to update a topo map with the hand-drawn track. One of the other great things about USAPhotoMaps, is that Doug Cox just keeps updating it, adding new features and keeping it current. USAPhotoMaps does lack some features, but all in all, it's a great program, and you sure can't beat the price. I believe it is particularly useful for people new to the world of GPS, who may not be ready to lay out...

A friend of mine and I were tromping around in the swamps of central Florida a few years ago. We both had GPS devices and we could see some cypress tress on the other side of a swamp that was about the size of a super Wal-Mart. We figured there would be hogs on that side of the swamp, so we headed there. (We were hunting wild boars) After trying to get there for an hour and a half and circling around three times, we gave up. As we left the swamp, my buddy looked at me and said "Mark that in your GPS and name it "Stay the Heck Out!" The canopy and the having to constantly change course because of vines and roots all combined to overwhelm our navigation skills even with two different GPS devices.
We were both skilled and experienced in using our devices. We had batteries and we even had ways of carry the devices so either an antenna was exposed or the device was stored in a clear plastic bag attached to the shoulder of my web gear. The trees got in the way frequently, so we would alk over to a place where the signal got stronger. Then we wouldtake a bearing towards another spot. However, we never made it across the swamp.

Great example of how mother nature can triumph over our technology.
Reminds me of some of the places I've tried to navigate before. Canyons, rhododendron thickets, etc. Sometimes you just can't get there from here!
