1. The front yard of the house where I lived from ages 2-10. There was a giant oak tree that shaded the whole yard. I spent many happy hours playing there. I don't really remember what I spent my time doing, but I think I sometimes made acorn stew.
2. The main quad at Notre Dame (aka "God Quad" because that's where the Basilica is). The golden dome towers over one end of it. The interior of the quad is an arboretum with tons of different trees. It's gorgeous and serene, and it's where I first fell in love with Notre Dame.
3. The kitchen of my grandparents' farm house. The best time was in the morning, with my grandma making eggs and bacon, homemade bread in the toaster, and my aunts and uncles from down the road stopping by for a morning chat.
4. The courtyard at my law school. You can sit in the courtyard's clean, comfortable chairs and tables for hours, enjoying the weather, studying, and chatting with the many passersby. Also, I made most of my law school friends in the courtyard, so it holds many fond memories.
5. Broadway Avenue in Capitol Hill in Seattle. This is the sort of hip shopping/restaurant district in Seattle. What made it great was that in addition to the abundance of Thai food, feather boas, and used books you typically find in such neighborhoods, it also had two major grocery stores and a small Target-type store, so you could actually live there. For six years, I lived within two blocks of it, and I rarely needed to go anywhere else.
