Re: Possible Country Records for the US
Richard: The preferred means of recording coordinates is through use of a handheld GPS unit. A popular Garmin model (the eTrex 10) sells for under $100. You can of course spend much more, or spend a little more and buy a used Garmin CSX that does a better job at getting sat signals in forested areas...
