Licesed FM stations are bound to complain, just because you're out there, interference or not. The interference they're really most concerned with, is interference to their ability to make money. This is why licensed stations routinely file objections to the proposed licensing of ANY new stations in their areas with the FCC.
It would be a good frequency to get heard on, but, anyone who keeps track of such things will instantly know that you're a pirate station, and it could be reported that much quicker. If it were me, I would look for a clear frequency somewhere above the educational portion of the band (92.0 MHz + ?), and "hide" amongst the licensed stations. (There may be more clear frequencies from 88 to 92 MHz, but you're more likely to stick out there also as "something that doesn't belong"... but then again, a station playing bluegrass music might be temporarily mistaken for an NPR show...).
