Bicycle Austin forum

Hi All -

I moved to Parmer @ Mopac from Dallas a few months ago and am looking for some good paved bike trails.  I have a road bike, but I don't like riding street because honestly, the thought of a 17yo girl txting her boyfriend in a suv approaching me from behind scares the 5#!7 out of me.  For anyone who has been to the Arlington, Tx area, my old ride was at River Legacy Park, it had a 7 miles in trail that was paved, looking for something similar, hopefully longer, out in North Austin, I've heard Lake Pfluegerville has a nice paved trail.  Any advice will be appreciated and TIA.
