TinkerbellMama, whatever you do, do not, I repeat, do not try to walk to the WM down from Crossroads. It is a heavily traveled road with no sidewalks and several interstate exchanges.
There IS a grocery and shopping center at Crossroads that you could get to from DTD but the prices are very high and there is not a whole lot of choices but it is better than risking your next out on the highway.
If you really want to go it might be worth a cab fare for you as it is not a long distance though.
If I was going to be there when you are I would take you on a shopping trip though.
