(AREA) -- Teachers are encouraged to reserve a date and time for students to attend the 18th Annual School Tours at the Thumb Octagon Barn & Agricultural Museum in Gagetown. The educational field trip-for Preschool through 8th grade students-allows the children to participate in up to 24 stations that depict rural Michigan in the early 1900's. The guided tours will be held during the school day on Wednesday, May 8th, Thursday, May 9th, and Friday, May 10th. Tours take about 4 1/2 hours, but shorter tours can be scheduled to meet the needs of the students and their schedules. Each student and chaperone brings their own lunch. Tours begin at 8:30 a.m. with the last beginning at 1 p.m. The cost is a donation of $2 per student and chaperone. The tours are held rain or shine. This year's theme is "Soybeans and Related Products." In 2012, about 1,000 students from six counties attended the educational guided tours.
