Get thee to Traillink.com and do a search for mup in the DFW area. I just did a quickie and found over 70. Start there and avoid all the cars until you feel right in the saddle. Then try on road. Having health issues myself, heart failure, I know the importance of some type of exercise. In my case it is cycling. Get out on the bike away from the cars and you will find that cycling will be an enjoyable experience. Ride ON
