Hadn't thought of tree cover affecting the usefulness of GPS ...
I've learned a lot in the last few months. Any recreational unit is only going to be accurate to within 20-30 on the best of days. For most of us that's plenty good enough.

I've got an etrex legend. I think the newer models might be a bit better, but wow after helping out some pros that were using professional grade GPS units ( $5000 each!!) that are accurate to within 12 inches, I'll never look at doing home made tracks the same way again.

Also, did you know there are web sites out there that will show you what times of day are best to be out to get the most satellite connection? I know, way too much info....we've learned a lot on our mapping project.
