Unfortunately, Jax was sucker punched a few decades ago with "easy money" from the Feds and bet on the wrong horse, the $ky-high-way. Had we turned down that money, today we would probably already have a far more useful and economic development friendly streetcar system.
You can thank the $ky-high-way for sucking the wind from the sails of Jax rail transit (not to mention scarring Downtown advancement) by diverting both money and political capital from these far better transit alternatives. That is why I insist killing the $ky-high-way is the first big step toward getting ideas like streetcars to become reality here. For now, Jax is a one horse town and its time we rode the winner and got off the loser.
