I worried at first that using CD's while out and about would be a hassle. What I've found is it's no big deal! Sure the diapers take up more space in the diaper bag, but all in all it's really not a problem.
I usually keep 2 BG's in my diaper bag, a few cloth wipes and a wet bag. This is the one I use from Target:

It was $12.99 at Target. I only have 1, but I really could use another one. It's on my list! The only reason I need 2 is so I have one while the first one is being washed.
It's just a bag with a liner that zips! You just throw the diaper/wipes in the bag and bring it home to wash. But make sure you wash the wet bag with the diapers! You don't want to leave a poopy mess behind! :)
Before my days of cloth wipes I use to throw the disposable wipes in the diaper and put the whole thing in the bag. And then I would just wash it all. Turns out it's no big deal to wash the disposable wipes! In fact I would be willing to bet if you wet them you could re-use them! They come out in one piece and very clean :)
