I went last February when it was held at Earleigh Heights Fire Hall. This year it's at a new venue, Glen Burnie Moose 1911 Crain Hwy. Glen Burnie, Md. 21061.
The dates are February 15, and 16 (Sat & Sun.) 8:00 a.m. - 2:00 pm each day.
It is worthwhile, and a good winter activity. There are representatives from D.N.R. you can chat up on various issues, you can buy your 2014 license, there'll be lots of new and used tackle to pick through, and I am sure there will be plenty to eat as well (last year there was pit beef, oysters, hot dogs, hamburgers, beer and soft drinks). Here's the link for anyone who is interested:
