We had an old mini van that worked the bes to be honest! We would just lay down bunk plastic, pull out the seats, and Cloudy would load right up through the sliding door. I'd ride shotgun and hold him, hubby would drive, and he would ride with his head between the bucket seats up front looking out the windshield. No, it probably wasn't the safest if we ever got into an accident, but, Cloudy is well trained to stand, respect space, etc, so we never had a single issue with him acting up, etc. Was a ton of fun to take through drive throughs, brought a TON of smiles to McDonalds workers.
We did have one "issue" once after a show. I fell asleep while holding him, and hugged his face apparently in my sleep. Hubby said his face had the biggest buggy "Uh, get her off of me" eyes ever.
