This is one of our better liked connectors to get to Catoctin Mountain from the general DC area. It beats taking I70 out to Frederick. There are a fair number of houses with a number of slow towns to go through, but it's generally a nice ride.
But don't take it too far into Westminster. Traffic just sucks there. I will have to go back and explore for a better way around Westminster. We generally like to take 97 up to this route, but 97 is also starting to get built up as of this writing June 2023.
