Buzzrules,
I have seen tons of police and then times when I have seen none, but, knowing what "bears" they can be, I procede with caution and only go max. 10 miles over the speed limit. Let the others run me over, they can be the "bear bait" , LOL.
The highway from Tampa to Lake Buena Vista (WDW) is 65 in most places, so, assuming a ten mile an hour over the speed limit, you are now going 75, with all the tourists on the road, most NOT having a clue as to where they are going, it seems a little silly to go any faster. Just MHO and this from a true leadfoot in CT. LOL.
