mid/late November might be another good time to fly the Guads but NM Pres Day is not the fly-in time.
The pres day weekend is indeed 19 Feb. The holiday fly-ins in Southern NM are generally in line with Fed holidays since so many folks work for the Fed Govt (White Sands, Holloman AFB, etc). That's why Dry Canyon has a Columbus Day fly-in: the base and test range are observing the Fed holiday.
I've not flown the Guads yet. I have heard many good stories though. Top land if you can is one of the pieces of advice that I have been given since the retrieve can be long..... kinda like Dino in that regard. Also was advised to be sure my spare tire was in good shape.
Back in 2000, CB, LW, and I looked at the drive to the Guads and we estimated 13 hrs from Denver. The three of us took two vehicles and went to Dry instead that weekend, an 8-1/2 hour drive....... 3 great soaring days with gains to 10K MSL and thermals as strong as 1K per minute. Craig wrote a great Flocker article that year.
Rusty Whitley and others in CO used to attend the Guads event regularly. Ping them for tips/knowledge.
I fly because it releases my mind from the tyranny of petty things . . .
