Outside Washington Law bookstore at about 19th and I streets. This is basically where I try to buy my books for school except when they don't have them, which is sadly pretty often because they have such a tiny space and no room for excess inventory. I went to get my books the other day and they had absolutely nothing I needed. Of course, this year it's looking like I'll have only one class that really requires books, so it's not really a big deal. Hooray for not having to spend $500 on books this semester!!
