re: Long rides in a car with a 1-1/2 year old advice.

download the app roadtrippers. It allows you to pick a route and then it will show you everything to stop at (land marks, parks, historical stuff, breweries what ever) within "x" miles of your route. Then plan to stop every 2 hours or so to let the little one run around a bit. IF he is asleep at a stop, pass it and keep going.

Ends up adding some time into the trip drivewise, but it gives you a reason to stop and hopefully it tires the kid out enough that when you finally stop for the night he goes to sleep.

Good luck and god speed
