The area is awash in ethnic festivals throughout the summer and fall, but one of the biggest and best is also one of the last. For three days at the state fairgrounds, 2200 York Road in Timonium, enjoy Irish music from local, national and international artists, plus dance, food, cultural exhibits, workshops and all sorts of vendors.
