boy, I sure remember the x-15. I lived at 177 sutter street which was the same street as the pioneer point motel. It was a pretty exciting day for us, as we were told it was top secret and we would get in heaps of trouble if we told anyone about it. I was talking with someone about this at the reunion, and who ever I was talking with, didn't remember anything about the x-15. (maybe they still thought it was top secret) have a great day,Jerri
