Do You Change Out Your Bag When The Weather Is Bad?

The only bag that I do this with is my JC Ramona. It's the most expensive bag that I own and I'm still not quite ready to take it out when it looks like it is going to rain.
 
I choose a bag that I think can handle rain drops. I've been using my Botkier Emily when the weather is dreary. I don't take any chances with my MJ's, Chloe, etc.
 
For some reason I get surprised by weather a lot, I'm unprepared so I have done my share of having my head mostly out in the rain but the LV is under the umbrella.....
 
I might avoid my suede ones, or ones made of unfinished leather that can get water spots. Other than that, I just use whatever I am using at the time. Most of my bags aren't really harmed by the rain.
