Sun salutations in the dewy morning grass, savasana under a pink sunset. No wonder free outdoor yoga was a big hit with Minnesotans last summer. Independent yoga instructors are planning another round of free al fresco classes for 2015 (many start in June). Look for classes alongside lakes Como, Calhoun and Harriet and Lake of the Isles. Or register for fee-based outdoor yoga at the Minnesota Landscape Arboretum and a host of other inspiring settings.
