The pick up rate was 66% this year vs 85% last year. With the shirts at registration, it was hard to miss and they were available any time registration was open. With the shirts in the exhibit hall, that limited the times when one can pick up a shirt. e.g. Shirts were not distributed on Thursday.
Some did not pick up the t-shirts due to the line being too long at the time they went by. I am not sure if they came back again.
