Walt Gajewski had a vision for the Farmington Farmers Market, and it came true. The well-attended market now has a pavilion with heat and bathrooms, and it’s doubled in size since Gajewski took over. Opening day is Saturday, May 4, and will feature the opening bell ringing, a color guard, a band, the mayor’s welcome and more. Each week has a different theme, including flower day Mother’s Day weekend, strawberry shortcake day and a corn roast.
