I swear there was a thread on this several months ago, but darn if I can find it. I'm trying to put together a Christmas list, and I really want a new bag for agility. Other than dog-specific bags, which aren't really speaking to me, where does one look for moderately sized bags with tons of compartments and a good, wide opening? I know there must be certain things such bags are made for, but darn if I can find them.
