OC, MD - one of my favorite places. In fact, we were just there a few weeks ago.
The only true LQS is Serendipity Quilt shop in Dagsboro, DE (
http://www.serendipityquiltshop.com). They are a very nice, friendly shop, lots of homespun fabrics there. Turn left onto Route 20 from either Rt. 13 or Rt. 113 in DE if you're going on the inland route. It's about a 45 min. drive from there to Ocean City.
When are you headed there? We won't be there again until the end of June. PM me if you'd like some restaurant recommendations.
