When I first started seeing the real truth about the "Truth", I attended a DC that was being picketed. They put a wall of young boys, all around 12 or 13 years old, in front of the picketers. I thought that was very abusive to do that to those children. There was one picketer that I recognised as a former Elder who was talking through a bullhorn but very personally and mildly to the people walking. All I could do was make some eye contact and smile.
Those events made me think long and hard... they were a big push towards my freedom, though I didn't realize it at the time.
Please take care in the heat, make sure you have shade and stay well hydrated. It may well move someone to make a change in their lives.
Oh, and I have several relatives that are going to be at that assembly.
