Yes, I was just going to suggest that... the Farmers Market on Atlantic Blvd. in Pompano Beach off of I-95... it's on the west side of 95, not even 1/2 a mile. I've layed over there before. Also, there's truck parking at Hypoluxo Road on the west side of 95 in Boyton Beach... just kill your engine. there's plenty of room to park there. large gravel lot and they sell Diesel there too if needed. The place regularly changes names, Shell, Chevron, Marathon, so who knows what the name is now. Realistically, if you don't shut it down past Ft. Pierce/Vero Beach area, you've got Boynton Beach (just south of West Palm/Lake Worth/Lantana) and you've got Pompano Beach Farmer's Market which is just inside of Broward County south of Deerfield. Then whatever they suggested above in Miami.
The Miami Truckstops though are infamous for truck vandalism though and accidents happening in the parking lots.
Now, if you need to get over to the west coast of FL, and your in the West Palm Beach area... there's 2 ways you can go... there's a few but the 2 main ways are: S.R. (State Road) 80, which is also Southern Blvd., straight west. OR... S.R. 60 up in Vero Beach, just west of the T/A up there. Personally I like going SR 80 myself, it's a nicer ride since they're doing construction on parts of SR 60 to widen it now. SR 80 out on the bottom side of the lake has some real nice area's... bring your fishin' rods if you've got some time... plenty of canals to try and get that bass.
