I'm in for at least Saturday and most likely Sunday. Frauenkommandant is undecided.
To complicate (but not confound) matters, one of my most valuable team members and her husband will be in town then from Chicago. They want to see the desert up close and personal so they may ride with me or we may rent a 4x4 for them to follow in. Or they may just take their rental car to Red Rock and hike.
Any more variables and I might just pack the tent and leave in the middle of the night!
As for the GPS, I don't know your Garmin unit but if you're building your route in MapSource on your PC and them importing it, I can use that map file. I use a WinXP touch screen tablet PC and MapSource for navigation. No big deal on this if it doesn't work out -- I've already mapped the route from 95 to Cima. As long as you know where you're going, that's enough.
I'll be sending a PM your way shortly.
