Jarchow is sponsoring a bill circulated this week to lower the state's drinking age from 21 to 19. On Friday he announced that he's running for state Senate to replace Sen. Sheila Harsdorf, who is leaving to take a post in Gov. Scott Walker's administration.
Jarchow's wife is owner of the campground. Jarchow listed it on his financial disclosure forms with the state.
