GPS Software for Aaron Frank's Mac

Aaron, try RouteBuddy. There's a demo mode where you can see your GPS's location and map routes around Santa Fe, but I'll bet you could pry them loose of a full version if you decide to review it to any extent.

It seems to be well-supported and has been improving steadily. I am told that the seed for RouteBuddy grew out of a frustration in having to plan motorcycle trips on a PC.

I'm probably going to buy it for trip planning long before I acquire a GPS.
