The Water St. Inn would be a good choice,walking distance to anywear in downtown and the city Marina.Friday night we have a car show and bring some of the boats on trailors downtown.We have people playing music on all the downtown corners.Plus the big crowd at the marina looking at all the boats from Poker Run.There are several people who spend the night in their boats.And yes we will make sure your 21 year old has a good time,just send her to 220 Lake St. bar,thats the hip spot.
