Nearing the End of the Road

I am now on the Overseas Highway, nearing the southern end of US 1, heading for Key West. On this trip, I traveled quite a bit of highway 1 in Maine, near its northern US terminus. Now I'm almost at its southern end. But the two ends are different...up north, you can cross into Canada and just keep going. In the Keys, you're at a dead end. You have driven as far as you can drive.
The road goes over many bridges, hopping from key to key. At times, it's almost like you're driving at sea. By the way, blow up the pic and check out the massive concrete power poles to the right of the road. Obviously, they're built to withstand the frequent hurricanes that menace this region. The spectre of these storms hangs over the keys, similar to earthquakes in relation to California.
