The rallies I went to were beyond packed and there were 2-3 times more people outside the arenas....
One in August '16 and one in 2019 and early 2020. The 2016 rally was in a fairly small high school gym which was jam packed...and felt like a steam bath.Many,many people denied admission. The other two were in a large auditorium in Manchester (the state's largest city). They were both filled to the capacity allowed by the State Fire Marshall (who was probably a Rat...quite a few empty seats)...but thousands were denied admission both times.
