4-H day camp only goes through 5th grade so this is the last year Spark is young enough to go. It didn't seem like such a big deal when Dancer was too old because Spark was still young enough to go for four more year. But this time there is no one younger.
In two years he will be old enough to be a day camp counselor like Dancer. If you still love camp after you are too old to be a counselor you can be a chaperon. I was there for the day as a chaperon because they have a ratio they need to fill for campers to adults. I spent the day setting and cleaning up activities so everything ran smoothly together and, of course, taking pictures.
