Thanks so much for all your date suggestions!
This is what Steve and I just did:
1) hired a babysitter
2) ate a delightful dinner at Carino's
3) went to Barnes and Noble where we set the clock for five minutes and set out to find the perfect book for the other person. Then we exchanged books and just hung out and read.
It was a lot like our honeymoon. Lots of good food. Lots of books. No babies.
We're kind of geeks at heart, really. And so it was perfect for us!
