Grissom Parkway in Myrtle Beach near Carolina Forest. Parkway is 2 lanes in each direction (total 4) and there is a concrete divider in the middle. There are no buildings or residences near this section of the parkway. Parkway speed limit is marked at 45 but the parkway feels like a highway so motorists have to consciously keep their speed down. I set my cruise control to 45 to keep from going over. There is no justification for this speed trap but the police make lots of money on tourists who aren’t paying attention. Note also that this whole area of Carolina Forest has police cruisers camping and waiting for the slightest violation so they can stop you.
