nthernigts, you need to know that Stu Osthoff ( BWJ publisher and probably inventer of the system) likes to take fresh fruit, vegetables and I believe milk on his trips as he often states.  Some of us travel with gormet meals and some less so.  Neither is right or wrong.  It's all in what you keeps you comfortable and happy out there.

If it works for you, then it's worth the money.
