Guess I should have left a little earlier. 301 was okay at first, but it took six hours to get to Jax. Sea of FL cars from there until I26 in SC where they disappeared.
An observation for those in FL who might choose to evac up I95.
I was on the way home last night. Traffic running smoothly on I-95 South at about 85 until a few miles north of I-26. From there it was stop and wait and wait and go a little all the way to Jacksonville (at least, that's as far as I cared about). That traffic that disappeared there on the way up reappeared there on the way down, and this time they brought all their friends.
I'll remember this in the future. If the storm looks like it may follow me up 95, I'll stay north of 26. If not, and I'm primarily concerned about getting home quickly, I'll stay far enough south of 26 to get the jump on a lot of that traffic.
I'm also going to research alternate routes (such as US17, which kind of stalks I95 and was, except in one place I had to route way around, virtually empty). Sucks trying to come up with a long route using minor highways while using a phone as a map, and Siri was in complete schitzo mode last night, changing her mind faster than I could react.
