Mainstreet Days is an event that is sponsored by JCI Hopkins and is an annual event that happens in May. It is hosted on Mainstreet, naturally, and is a way to gather with other members of the community to celebrate what makes Hopkins a great place to live. One of the biggest draws in the Mainstreet Day Arts and Crafts Fair, which has over 150 arts and crafts vendors who participate. This includes fine arts, jewelry, garden decor, photography, and so much more. While this is going on, there is also live entertainment and kids activities, and food vendors around as well.
