Wow, thrown off of a bus at Yeehaw...if that doesn't get you do some soul-searching, I don't know what will...
I started making the drive between Croom and South Florida back in the early-80s. Back then, I-95 had a break in it -- which I believe was between Ft. Pierce and Vero -- so places to cross directly east to west (or vice versa) were more limited than they are today. Anyway, I needed to cross over from east to west, from time to time, so the flashing light at the Yeehaw Junction was something I crossed under many times.
I've always had a problem with toll roads, in general, so I used to get off the turnpike there to reduce the government "suckage" of my wallet. You're absolutely right, though...there wasn't much out there then and I imagine that there's not much out there now.
