Mike, Your reasoning is much the same as mine. Some years back I did have a few guys to run with, but I had a hard time meeting up with them, because I had small kids. It looked for a time like we maybe we would have a few tracks and some options, but one guy found he liked racing his computer simulators better, another guy thought we did not appreciate him or something (still not sure on that one), I would meet some new guys at the hobby shops, but increasingly they were running one of the many digital systems and they had no analog cars and I had no Digital cars. and then I switched to concentrating on 1/43. Amazingly, I did on occasion meet up with a couple other guys in town interested in 1/43, but they quickly fell by the wayside due to job or family obligations. Needless to say running 1/43 can be a rather lonely endeavor and most guys just don't have the sticktoitiveness to make a go of it. My major attraction for doing digital or AC2car would mostly be being able to run a jam car! I don't think dead spots would be a big problem, because the track would be fairly open and flowing and cars should be able to move through the changer area's pretty rapidly.
I have a basic track footprint drawn up, but I am not going to post it, because it's really rough, and probably not exactly what I am going to do; I expect that I will most likely design it as I go. I intend to have a large banked turn at one end so I will start with that , and go from there! ;)
Once I have a track that can accommodate 1/32 cars I am sure I can get some guys together before too long! Dallas/Fort worth is a big place and there's got to be a couple dozen guys out there who might be interested, but as you said usually it's just me and a friend or my kids so I don't sweat other people likes or dislike and I do what makes me happy!
