April is National Poetry Month, and it is the perfect time to visit Montpelier, which transforms into PoemCity for the entire month. Organized by the Kellogg-Hubbard Library, this year the event displays 450 poems in the windows of 50 downtown businesses. The poets range in age from 3 to 94, include 200 students and represent 75 towns. There are also 35 community events and poetry readings scheduled.
