Hi! And welcome - I'm also in Maryland (outside of DC) and am also debt-free save for my mortgage, which is shrinking each month (yay). Glad to have you here on the forums!
Are you on the Twitter by any chance? I'm not as great as checking in here frequently but am on Twitter pretty regularly (@MsFinancier). Like @guyonfire.us mentioned, there's a good crew of us in the DC-ish area!
What's next on your financial goals checklist??
