According to Gateway Pundit (a handy source not an endorsement):
On Friday, the largest group, ‘The People’s Convoy,’ merged with another massive group when it arrived at its final rest stop in Hagerstown, Maryland, which is just 75 miles (90 minutes) away from the nation’s capital.
The convoy is now well over 10,000 vehicles long, including thousands of trucks. There are so many participants in the caravan that it has taken over three hours for them to get off the highway, and there is still no end in sight.
We will monitor, including watching out for a riot that can conveniently be made into a further Reichstag fire framing incident. DEVELOPING
