Severna Park, Maryland Roadblocks

When I was stopped at the sobriety checkpoint I was very nervous and very stoned but the cops honestly were not to bright about things. I made several obvious errors in my speech and still was not tested, although there were many teenagers my age being tested as I drove by, I believe they were going more on looks, I was dressed very nicely at the time, from what I could tell most of the people being tested were either in dirty clothing, black, or dressed expressing their individuality.
