Thanks, both of you! Great info!
I also found this link which was pretty helpful:
http://www.dallasnews.com/sharedcont...ails/more.html
It shows many bike trails in the Dallas area.
Also, even though I have yet to get to actually ride any of them, I'm loving this book:
Best Bike Rides in Texas.
There are some great sounding ones. I'd particularly love to do the Autumn Trails in Winnsboro or the Glen Rose ride (complete with dinosaur tracks -- we camp down there at Dinosaur Valley a lot so that would be a great weekend).
Oh yeah, KSH -- let me get a road bike and see where I stand. Right now I'm way too slow for you. But give me a little time and maybe I'll be able to give you that call!
