Being a gingersnap addict, I truly empathize on this point and direct you to the only somewhat passable substitute of Mi-Del Gluten Free Ginger Snaps (likely available at Whole Foods or other natural grocers  - I used to get them at Yes! Organic Market on Columbia in Adams Morgan).

I know you're in northern Adams Morgan, but Columbia Heights has a Vegan bakery, Sticky Fingers, that sells all sorts of gluten-free sweet and savory foods - and they're actually good! I don't have any dietary restrictions, but I used to stop by all the time when I lived up there. And it would be pretty funny if you wrote your blog from a Vegan bakery; you would find something that trumps the effeteness of the petite vanilla bean scones.

Here is a recipe for Gluten-Free Vanilla Bean Scones!
