Scott,
DC has middle of the road liquor laws, not the worst, not the best. The sales tax here is 1.50/gal, there is no sales of distelled spirits in grocery stores and liquor stors can't sell distilled spirits on sundays. Distilled spirits can only be imported into DC through someone with a valid wholesaler's license. I live here and know someone who is looking to get a wholesalers license. Actually, I recently looked into it too. There are a handfull of wholesalers here in the District. Let me know if you need any help out here.
