I have an 9 yr-old daughter and an 11 yr-old son. My son is way too cool for a WCB, but my daughter is thrilled when her box arrives! Each time she opens it there is a very quick and thorough sorting of items, and so far very few items wind up in the "meh" pile...and typically those are just the food items. IMPORTANT NOTE: Her dislike of the food is because it's difficult to find healthy, outdoor activity snacks that taste like bread or chicken nuggets. The rest of us grab the food and throw it in our own backpacks.
Additional IMPORTANT NOTE: Even though he's too cool, my son is always bummed when a box arrives for his sister and not for him. Hey - being that cool has a price.
