Thanks... I decided to grab the best of the three, but the one in the worst shape (which I suppose is a good thing)... the specialized and the wife picked the schwinn. I got the tires pumped up and we drove them around the driveway.... Rideable but needs some adjusting of the gears and new tires. I took them to the local bike shop... They are giving them both a good tune. I decided to tinker with the trek to get that into condition myself (it was probably in the best shape). The specialized was the boys & the other two were his sisters. Thanks for the links and advice. Happy trails.
