Years ago I was running a few km before work and there was a fat guy who started running the same path one day, after about 2 or 3 weeks of seeing him almost everyday I stopped and talked to him.  I ended up running with him for the next year or so until I moved away.    Chances are someone will help you out if you are willing, and prove you're going to put the effort in, most of the time (like it's been pointed out) it's the fattys who show up one or two times and then give up, why would you want to waste your time and energy on someone like that?
