West Main St
The Rapid City Police Department sometimes sets up in the area known to locals as "The Gap." This area is on West Main St., roughly between West Blvd. and Jackson Blvd. They ask questions about things they have no business knowing (what you’ve been doing, where you’re coming from, where you’re going, etc.) The last time I encountered this roadblock, they also had a twin roadblock set up nearby on Omaha St., roughly in front of the parking lot of the frisbee golf course. The last time I encountered this roadblock was on the first weekend of the annual Sturgis Motorcycle Rally. However, they set up the roadblock on West Main St. at least a couple times a year.
