Goodbye Earth Day, Hello Earthfest

May 24. The Hatch Shell.

That's when Cake, the BoDeans, Cracker, the English Beat and a raft of environmentally friendly companies and non-profit groups stage a free concert and celebration of the Earth on the banks of the Charles.

It's the 15th Annual Radio 92.9 EarthFest, just one of many green events scheduled in upcoming weeks. Find out more here.

Before then, cycle to work or play during Bay State Bike Week, from Monday, May 12, to Sunday, May 18. That Friday, May 16, also happens to be National Bike To Work Day, with several breakfast stands open for cyclists around Boston, including City Hall Plaza. Find out general cycling events this spring from MassBike here and about Bay State Bike Week here.

But why wait to bike? Today (sunny, highs around 80), looks like a pretty good day to start.
