As a quick test run, I opened up a map of my home area and downloaded the track log from my GPS, creating a map of the trails I ran most often last winter.

I imagine that MacGPS Pro can probably do everything that TOPO can do, but I found the former to be dreadfully difficult to work with. TOPO has much more intuitive interface, it's much easier to find the desired base map with TOPO. I'll continue messing with it when I get the opportunity, and if I'm as happy with it in 3 months as I am now, I'll delete MacGPS pro from this machine.
Green-up is only a heartbeat or two away. The sap is running full bore up the birch trees, and they've produced a record quantity of pollen. That yellow 'dust' that seems to be covering EVERYTHING up here is birch pollen. I can't help but feel sorry for those allergic to the stuff, and I'm very grateful that I am not. I'm thinking all these trees will be leafing out within just a couple of days.
