How to Pack Dog Food for Your Vacation

So, you're heading up to the mountains for a few days, and you want to take the pups with you.  What are you going to do about dog food?  Pay way too much for a small bag in a mountain town grocery store, when you already have plenty at home? No way!  Fill a cheap zip-top bag with kibble and hope it doesn't explode in the car?  No thanks.  Try this instead...

I love this idea, because it makes use of something I hate throwing away: bed sheet packaging!
