The carrying member


11


also has a top portion


16


. The top portion has at least one aperture


17


for allowing litter to be placed inside the carrying member


11


. In addition, the carrying member


11


may be partitioned into a plurality of sections


18


. This allows a user to sort out different types of litter


30


. In this embodiment, each section


18


has an associated aperture


17


in the top portion


16


of the carrying member


11


for allowing litter

33


for crushing aluminum cans may be coupled to the carrying member


11


. The can crusher


33


has a first portion


34


that is coupled to the top portion


16


of the carrying member


11


. The first portion


34


has a first surface


35


for supporting an aluminum can placed thereon. The can crusher


33


has a second portion


36


. The second portion


36


has a second surface


37


designed to crush an aluminum can against the first surface


35


of the first portion


34


. The second portion


36


is hingably coupled to the first portion


34

.




In use, the distal end


22


of the hitch portion


21


of the trailer assembly


10


is engaged to a vehicle


23


or animal


41


for towing. As the trailer assembly


10


is being pulled along, pieces of litter


30


are picked off the ground and deposited into the carrying member


12


. When done, the trailer assembly


10


is moved to a desired location to deposit the litter


30


. The latch member


24


is then unengaged from the receiving latch portion


25


and the carrying member


11


is pivoted relative to the main support portion


19


of the frame support


12


until the litter


30


falls out of the carrying member


11


. The latch member
