It could happen any day now. A really toasty, bone-warming day will finally dawn in downtown Schenectady, and when it does the doors at Anthology Studio will be propped open to catch the spring breezes. “We’re itching for the first day that we can open our doors and let the air in here. Springtime is really exciting for us,” says Evan Euripidou, owner of downtown’s only florist shop, on State Street across from Proctors and the Hampton Inn. Like the spring air, just about everything about Anthology is new, fresh and infused with youthful energy.
