The last road trip I went on was to visit the parents for a week. With all of my underwear 300 miles away, and just a 2nd suitcase full of diapers... well... "guess you're wearing nothing but diapers this week!"
But it's nice to have the option, not that it happens often anymore. Maybe a few hrs for one day in a month, if that. I choose to keep it enjoyable as much as possible. So if it's going to be a major hassle, I just don't. Besides, then while I'm out I can think about how much I'd rather be padded, and picture those tall, white, soft, crinkly stacks of diapers waiting in the cabinet at home for when I return. Think about how I used to yearn for diapers and wish I could have some, and know that now I can, great ones are right there waiting for me when I get back home. Padding back up after a break like that can be quite enjoyable.
Maybe reason enough to go without for a little while?
