I just was offered a job I applied for at a local summer day camp which hires teachers as group leaders. I haven't worked at all since DD was born six years ago, so I'm sure it'll be weird not having the weekdays to do all my usual stuff, but I'm excited about it.
The best thing is that children of staff members get to go to the camp for free, and this is one of the best camps around. I would never, ever be able to afford it normally. There's an excellent counselor/child ratio and a group leader with each group (I won't be with DD of course), and they have a beautiful campus with great facilities.
