I have one in my car but usually one use it if I remember to bring it in with me.
Other wise I usually get wet. We went to Olive Garden and it was downpouring and I ran in the rain, it was great, unfortunately I forgot I was wearing a see through shirt.
Oh well, it was fun. I like walking in the rain as long as my cell phone is at home and I am not going to be going to anywhere I need to look decent.
