right before this post, brusselsprout mentions how important it is to have zip locks... Deb says they are everywhere, but I for one always make sure there are some in MY BACKPACK. everyone has different ideas on what to bring, this is just one person's thoughts, it may not match up with your own personal list....
I always bring an assortment of sizes of ziplocks. Especially handy when you get too many johnny cakes @ breakfast and want to keep them for a snack later in the day!
