In the median, at Minneola, two patrol cars one facing North and one facing South, difficult to see in dark valley. Or, during the day on the Right side if heading south, in unmarked brown/silver cars. Speed limit changes from 55 going downhill to a sudden 45MPH on the US HWY. There is a sign for reduced speed ahead, but the actual speed limit sign can be invisble and it’s difficult to slow down quickly in HWY traffic that isn’t slowing down. Also, going back uphill the speed limit changes back to 55.
