Guests gamely slipped into construction-site couture for the Habitat for Humanity Hard Hat & Black Tie Gala at RiverCentre in St. Paul. Donning tool belts, construction tape ties, reflective vests and work boots, Habitat supporters enjoyed dinner and a program, then danced the night away to the music of High & Mighty. Funds raised from the evening — including silent and live auctions — benefit Twin Cities Habitat for Humanity’s expanding homeownership program, which helps families find affordable housing and succeed as homeowners.
