What the state highway patrol peeps are saying is that speed doesn't really matter at all over holiday weekends. Everyone's drunk anyway.
"Excessive speed does cause crashes, whether the speed limit is 55, 60, 65 or 70 mph," a high patrol spokeswoman said. "But we find more impaired drivers during holidays and holiday weekends."
Here's the upshot: expect way more cruisers on the roads, folks. Drive safe and drink responsibly.
