When we take any car trip over 45 minutes, we look for gas stations with "Pet Area's." They are surprisingly clean and have a big enough space to get a baby's wiggles out without running in front of a semi truck.
Kinda funny how much people cater to animals. Our friends would sometimes compare their miniature dog to our infant son...which I could only take for so long! One night, while we were all at dinner (and I was entering and leaving the conversation every 5 minutes to chase Lincoln), they made another ridiculous comparison, and I started laughing and said, "you act like your dog is a baby! Try having - or even taking care of - a baby first before you compare your dog to our child." I regret how rudely it came across (especially since they were hosting the dinner party), but c'mon.
So, gas stations - how about some stir-crazy, "Child Area's?" You can even keep the pail there, since we threw Lincoln's dirty diaper in it! Take that.
