Several of us from the office are riding Thursday from the parking lot at the north end of Taylor street in downtown Fort Worth leaving around 5:15.  If everyone is up for it, we'll likely go climb Burton Hill which is about as steep as I know of in the city and reachable just off the trail system.
Glad to have anyone join us.  My cell is 817-995-5551, call if you're running late and we'll wait.
