It’s always been that way, but it does seem even more pronounced now. If I had to guess, it all stems from the lack of hobby choices in the westoplex. There is virtually no AMP scene here, very little in the way of studios, the pimps gravitate to Dallas; with all that activity over there, most of the true independent ladies that might prefer to work here end up moving or commuting there as well. Local government’s toleration of storefront sex is likely a big factor in all this, too.
All things being equal, Dallas and it’s suburbs ought to have more activity just based on population. The gap, though, is much greater than can be explained solely by demographics.
