RANT ABOUT ROLLING BACKPACKS!!

[sea_mi_bufanda]

I have to write a speech about rolling backpacks in compet and I've come to a mind block. I've said everything I feel is needed, and it is still only a page long (without double spacing though)

So it would be a HUGE help if you guys could tell me some of your thoughts on rolling backpacks. Negative or positive. But please don't just say, "THEY SUCK!!" Try to think of something a but constructive.

Thank you much!!
