8pm Fri Oct 12. Roadblock was removed before 10pm, so likely wasn’t for checking sobriety.

Cars were backed up and police were moving very slowly. I’d had nothing to drink, so legally turned around to take another route. A police car quickly pulled me over. Relatively polite officer asked me where I was going, and for my license. After an acceptable (less than 5 min) wait, I was allowed to leave. No explanation was given for why I was pulled over.
