Leaving Florida, how is I-75 north traffic

I don't know how helpful this will be, but here in the Florida Panhandle spring break is pretty much over. Traffic has died back down to about normal. The snowbirds generally leave before the spring breakers arrive so that won't be an issue.

In addition, most spring breakers don't wake up until after 10:00, so if you're on the road early they'll still be in bed.
