When we first moved here, and before there was anything south of 466A, we noticed that we would often get a wave...and happily returned it.
We also noticed that it seemed to occur more frequently toward what was then, the southern half of TOTV.
I'm guessing that 'in general,' newcomers are more likely to wave and that the longer they are here...the less likely they are inclined to do so.
I support this wholly anecdotal observation, on the fact that it seems in my travels south of 466A...people are still more prone to waving.
