You can’t see it, but wind is all around us — and might even serve as a good source of renewable energy. And where better to celebrate all that than at a beautiful lakefront park? That’s the thought behind the second annual Euclid Wind Festival, which will feature the biggest concentration of wind turbines in Northeast Ohio. You can dig those cool effects today from 4 to 9 p.m. at Kenneth J. Sims Park in Euclid. There, you can take tethered hot-air balloon rides, see on-land wind surfing demos and hear Pieces of Eight play a concert on the beach. There’s even a beer tent. (Niesel)
