Did you know the Metroplex is like the size of Connecticut? Anyway, I need to get all the way over to that part of town and sniff around, but it looks like they finished the bike path up (and I do mean up) the west side of Belt Line from the dam turn-off* to Sleepy Hollow Drive. This runs past Joe
Cool Pool Lake State Park and through, uh, something of indeterminate origin and function (help me out, here, gang).
Edit: It's an observation deck! It affords views to the west across Joe Pool Lake
The similar, smaller structure on the path to the south is art.
*Corps of Engineers has closed the path across Joe Pool Dam. Damn.
