Jacksonville traffic is the weirdest thing to me. Whenever I travel there on 95 or 10, the traffic is usually ok. You get off on JTB or University or Beach and all of a sudden there is just random stops. No rhyme or reason, just 100s of cars in a small area (no accident, no police).
Orange Park area is even worse though. Everybody rides on the same darn road (Blanding). Yuck, I would sooner drive all the way to Fletcher across Jacksonville rush hour traffic than to ever drive to any of the Clay County schools during rush hour.
There will always be the balancing act of how far will people be willing to drive vs how "nice" of schools do we insist on. I think for Fleming Island, PV, Nocatee, those adults made those decisions. "I want very nice house, no riff raff, and nice schools even if it means that I have to drive an hour each day." I don't think they are going to change their minds in the short term or at least not enough to cause Bolles to have their admissions office flooded with people willing to pay that cost.
