Hartwick College’s Theater Arts department is presenting “A Year With Frog and Toad: The Musical” on Saturday at 10 a.m. and 2 p.m., and Sunday at 2 p.m., in Slade Theater, Yager Hall, on the Hartwick campus. It’s based on the beloved children’s books written by Arnold Lobel – a series that chronicles two friends, a cheerful frog and a curmudgeonly toad, and their adventures together. Admission is $10 for the general public, and $5 for all students, children and Hartwick faculty. Children 12 and under are free with a paying adult.
