Hi again Ari and welcome David!
David - since you're new to the LEAF market in Cleveland, I'll let you know of some charging stations that I know of that may not be "on the map."
First, there's the locations downtown. Ari has posted one a few posts above. It's located at the Uptown development by University Circle. There are actually FOUR chargers behind Constantino's. His directions are spot on. There's also one at the Baker Electric building (E 70th + Euclid, I think). I haven't had good luck there, but supposedly it's fixed.
Out in the suburbs, there is a charger at the McDonald's in Garfield Heights (Rockside Rd). There is also a charger at the First Unitarian Church in Shaker Heights (solar array too!). Besides that, it seems that all Nissan Dealerships also have chargers. I've never had any problems at Ganley Nissan in Mayfield Heights. They leave their parking lot open 24/7 so you can always get a charge if needed.
On another note, have either of you heard of National Plug in Day? http://www.pluginday.org/
There isn't an event in Cleveland, but there is one in Columbus on September 28th. I'm planning on going (there's a charger in Medina and Mansfield which should allow the trip to be made).
However, we could possibly have an event in Cleveland. I'm not sure what is involved because the events seem organized on a local level but I'd certainly attend and help if others want to help set it up. If not this year...maybe next?
And to answer your question David - I know of a owner in the Mentor area with a red Leaf (Jon). And I recently met a silver owner from Solon (had Wisconsin plates). So with Ari's numbers, that's 7 total.
