On highway 501 North Under the Great Pee Dee River
We were returning home from Myrtle beach SC and were on highway 501 heading north. As we crossed the Great Pee Dee River, a SC Highway Patrol Officer jumped out from under the bridge and pointed something at our car. It was a radar gun.This was scary as he waits until cars are about to cross the bridge then pops up. Up the road about a half mile are several highway patrols which catch motorists. This is where Marion county(The poorest county in SC) changes to Florence. this is a trap as tourist leave SC. I wasnt speeding but saw a number of motorist caught. What scared us was how this guy waits until you are about to cross the bridge going north then pops up and points something at your car. It takes a second for the driver to realize who who pointing at the car. Never seen that in my entire life of living in SC.
