picking up lots of beers?

anyway, lol, that's what i was gonna say...how can miles be put on a bag? I would think it would be more of a function of how much the zippers are used.

I mean ****, I have a mouintainsmith backpack that i have used for 8 years constantly and the zippers have never broken, and I've put that bag through hell. Don't know how many miles i walked or rode with it though.
