Parts of Maryland do indeed recycle...it is largely a county/city thing, but areas with enough population usually do.

(Having a LARGE van, and living in MD, I can sort of suggest that IF you were to find that you 'accidently' discovered some suspect bottles and cans, and had no notion of what to do with them, and were to bag them and to locate me as you are leaving, that I could manage to get them to a proper recycling place.)
