I had a similar experience a couple months ago on our way to Key West via Cocoa Beach. If any of you have ridden "Florida's Turnpike" you'll surely remember this. This friggin' highway has more toll booths than New Jersey! Seems every town, city, county or whoever feels like building one has toll booths every mile and a half! Well when you pull up to give the nice attendant your spare change, you have to get pretty close...and it puts your right boot smack-dab in the antifreeze/oil/tranny puddle. Did the fandango a couple times before I figured out my wife was making it worse by shifting her weight around fishing for more change.
BEWARE anyone headed south...I'll take an alternate next time to be sure.
