It's been a mild winter so far (especially compared to last year), but a bad case of cabin fever doesn't depend on the weather. A couple of weeks of gray skies and early sunsets are enough to make even the staunchest lover of winter start dreaming about blue skies. Schlafly's always-popular Cabin Fever takes place from noon to 4 p.m. Saturday, January 12, at the Schlafly Bottleworks (7260 Southwest Avenue, Maplewood; www.schlafly.com), and it provides all the impetus you need to get outside and have some fun. More than 40 varieties of beer will be sampled outside (tickets include a commemorative tasting glass), and food will be available to purchase on the festival grounds and inside the restaurant. Cabin Fever is a rain-or-shine event, but if the weather gets dangerous, a rain date is planned for January 19. Tickets are $35 to $40 and going quickly.
