When I looked at the Google Map for directions on how to get to Amelia Island from Jacksonville, it showed Highway A1A as a straight line extended across the water. I made the logical presumption that I was seeing the depiction of a bridge or causeway.
So you can imagine when I showed up to Mayport, FL, I was rather pissed off to find that A1A stops dead in its tracks at the water's edge and that you have to drive your car onto a gigantic ferry that takes you across to Fort George Island and beyond on the other side. Then I found out it costs money. And they want exact change. And they don't take plastic. And they only run at very specific times. Furthermore, the palpable Department of Homeland Security presence in the area (because of the adjacent naval base) made the whole place a total drag to be around.
So be warned, kids. Don't do like I done did. Go to Amelia Island the long way 'round.
