Do you attach your keys to your....

I have before yes. But right now I'm using the legacy stripe turnlock keyfob so I just threw my mini skinny in my bag with insurance cards in it. I actually just did that about 15 minutes ago.
 
No - I completely detach the key ring from the skinny. I just haven't been able to allow myself to be that much of a minimalist!! I think I'm doing good by deciding to get a pouch for grab-and-go!!
 
I attach my keys and keep my metro card and startbucks card in the pocket. I then keep it in my jacket pocket or an outside zip pocket on my bag. The three things I need in the winter quickly! My hubby and I have a contest to see who can get there keys out faster...this way I always win!
