The Pella Convention and Visitors Bureau is joining the returning Iowa State Fair to promote the community to visitors from around the state and country. Jill Vandevoort with Visit Pella says the organization filled all of its volunteer slots for their booth at the Varied Industries Building over the next 11 days. Vandevoort says continuing to keep Pella and the Red Rock Area in mind for fair-goers is a big boost to fall and spring tourism, especially when promoting the upcoming Tulip Time celebration.
