Last summer my buddy and his two kid, myself and my two kids are headed over the pass to Lake City from Silverton, before we get to the pass he gets a flat, so we change it and keep on trucking. We make it over the passs and are still 20 miles from Lake City. Bingo, he loses tire # 2. We load all the kids him and I in my tacoma. It is tight, my oldest daughter is in the front middle unbelted. I drive like grandma, paranoid floyd to Lake City, not high risk but this is just one example of it would be nice to turn off the passanger bag, throw my buddy in the back, (sorry Jon) belt my daughter and head down the road.
We did 3400 mls. that trip and 12 year old daughter #1 and 10 year old daughter #2 had their times when I wish I could have put one in the front and one in the back seat. Daughter #1 is on the borderline of being big enough to be in the front sear anyway.
