The Citgo Truck Plaza on Hwy 17 is where I left my big rig. There's a good restaurant buffet here, but I didn't use the showers. The bathrooms were down half the time I was there. Anyway, this place provides a good landmark for finding your way back into the old downtown off of Hwy 17. Needless to say, I didn't spend any time in the "new" part of Haines City.
There's a local bus system that runs around town called W.H.A.T (Winter Haven Area Transit). I didn't use it as I walked just within the old central core of the city. Some locals may not even be aware of the system but it's there and I did see a bus go by. I think it costs $1-.
