Srsly. Snother mystery. I think this says more about the quality of the camera on my GPSR than anything else. I don't reccomend getting a GPSR with a camera; your cell phone was better like 10 years ago, no joke. But check the web before you select, cuz I make no claims of perfect accuracy in my from-the-top-of-the-head descriptions. ;)
Enjoy the walk! If done right, you could get a 5 mile round trip walk in by the time you're done!
