Made this trip by car with my wife to the Park and Terlingua on a brief vacation seven years and have been trying to find the time to get back ever since. It's hard to believe the magnificent area is so unknown in the US. Sold the big cruiser last summer, thinking at 70 years old, it's time to put riding aside and settle into old age. . . . but this is definitely not working at all. Picked up a great deal on a '07 Burgman 650 Executive last week up in Northern IL,and getting it accessorized for Spring. Being a fair weather rider, (low to mid 70's min.) I'm planning to tow the Burgman from Southern IL to the Park and ride for about 5 days, including Brewster County, Marfa, etc. At Marfa, I'm hoping to get a glimps at the old "James Dean" windmill from the movie Giant. I'm assuming to get these temperatures its got to be no sooner than late March? Anyone from this area who is familiar with the annual temps?
