I just went to the "Seattle Street of Dreams" with a couple friends. I had heard of it before - really pricey houses opened up for you to walk through. Whee. This year, it was maybe a quarter mile from my home.
I saw some neat things - some doorknobs (more 'handles' than 'knobs', really) that I liked, and some semi-permeable driveway approaches that would be nicer than the jungle I currently call my driveway.
But, for the most part, I learned that if I had $1.975 million, I would do something else with it.
