I do the 'walking' bit to move leaves also (I have to get a bunch from the back yard to the street where they are collected)....but for LOTS of leaves, I go to the hardware store and buy a roll of heavy-duty plastic (3 mil.?) and cut it to about 12X15 ft. Blow the leaves onto the plastic...until you think it's full enough, then grab corners and made a bundle and drag it! Takes only a couple of tries to decide how much you want to drag. If you are reasonably careful, a sheet will last several years. Small tears can be patched with duct tape.

Been using this trick for about 18 years now.. (I used to do it with big plastic trash cans, but the sheet plastic is 6-7 times larger and 10 times easier to load.)
