I went with Pat, who also does the collecting for the two-sort recycling pilot program in the Seward neighborhood.
Don't set your recyclables out in plastic bags -- they get all tangled up in the machines at the recycling facility.
The other strenuous part: paper. Also heavy. See how Pat is throwing the paper way over his head? He does that more than 100 times a day. And the panels on the sides of the truck raise as the paper compartment gets fuller and fuller, so the opening for throwing paper in becomes smaller and smaller.
