Summer Nanny Needed!

We are in need of a nanny for our 9 yr old daughter and 7 yr old son this Summer (and likely future summers) Full time support is needed. We have had a nanny every summer so far but she is now an engineer :). We maintain a regular schedule and both kids are on swim team during the summer which gets them up and out the door. We like to make sure they are getting out and enjoying the summer be it a hike, bike ride, the zoo, library, city museum, made, or the pool. Owning own vehicle and non smoker are musts.
