All the kids' clothes are going to get stained anyhow, so don't bother packing anything nice. Anytime you can't get a stain out of something, just stick it in the "save for camping" box (which you may occasionally dig into on "don't feel like doing laundry" days). Now you can let your kids (or your husband, or yourself) crawl in the dirt without worrying about all the scrubbing and pre-treating you'll have to do when you get home. This is also a great opportunity to pack ugly clothes that you have received as gifts from relatives. This comes with an added bonus, because you will probably take lots of pictures on your camping trip, which you can then send to said relatives, who will be touched that you appreciate their gift so much. "Look, Aunt Ellen, we're wearing the matching puppy tank tops you crocheted for us!" We love them so much, we only wear them on special occasions when no one we know is around.
