I received this today from the Ohio City Bicycle Co-op:

I'm doing an unprecedented thing for me, and sending this to everyone I
email (Sorry if you consider this "spam") because I think it's
important that folks get together on this -- especially after reading Al
Gore's Op-Ed in the New York Times:
http://www.nytimes.com/2007/07/01/opinion/01gore.html

Some of you are not in Cleveland, but look at this invitation anyway,
please, and if you're not, I think you can find an event near you by
clicking on the "find an event" at the top, by "event central"...
I feel strongly that we can all learn something from this kind of
event, so here's the boilerplate from Live Earth, and if I don't see you
(with your bicycle, I hope !) at Great Lakes Brewery on Saturday, I hope
you will attend an event near you if you can:

You've been invited to attend Audubon Party for the Planet. Go to
http://www.joinliveearth.org/page/event/detail/wxy#rsvp to RSVP.

I hope you'll do something fun and meaningful for the planet this
Saturday -- if not by attending a Live Earth party, then by riding your bike
somewhere!
