Postgame:
Sweet mother of confusion I am sore as fuck. Wound up marching with the Pirates (although I fell behind a lot), which was good because my second bag of flyer holding failed before we got underway and they have a cart to dump things in. As part of the prep stage, I piled up all the flyers such that there were no twinsies next to each other, or even particularly close. This turned out to be really important, because I handed lots of people more than one flyer as I went.
The small multifolds were a huge success. There were a number of occasions before we got underway where someone balked at the full half sheet flyers but accepted a multifold when I said "take this, it's small." As always, "congratulations, you're a pope!" was very effective at getting people to take flyers, and the followup "and you're a pope!" to the neighbor had a high success rate.
Ran out before the last leg of the parade, I'm not sure I packed too few flyers, I may just have to be more conservative with the multiples and not pre-flyer the other groups waiting to march. I'm considering solutions to the grabbing more than one problem, potentially using latex gloves or designing some kind of separator to load flyers into as part of the prep. I also need to organize my restocking better, lost a ton of time running to catch up with the cart where my shit was. Wouldn't be an issue with a non-parade flyer run, though.
I miss doing this shit on the regular.
