Southern NH ashtanga yoga

As far as I can tell the studios that currently offer mysore ashtanga yoga or ashtanga based courses are Earth and Sky yoga in Wolfeboro, East West Yoga and  Portsmouth Yoga Shala in Portsmouth, NH and Studio 72 in Portland, ME. So far, I have only visited Earth and Sky which offers an abbreviated but challenging ashtanga inspired 1 hour 15 minute class. The picture above is from the studio and it's surrounded by water on two sides.
