Unfortunately, other than perhaps the dead of night, no really good time to go thru Florida on I-95 and I-4. We went in May and aside from getting around DC, that whole drive thru Fla. was the worst part of the trip. Seemed like road costruction every step of the way. My nerves were on edge until we actually sighted the MK signs.
We're driving again in Sept. and I'm finding myself not looking forward to it. This time we'll go AROUND Jacksonville, but other than that, I can't think of much else to do except "grin and bear it".
