I said a few things in the original thread...
and yes, your friend will HAVE to go over to Toronto I expect in any case, since the islands she will be at are pretty small, especially the residential parts! Most is parkland, or the small airport, or the islan beaches. Not a lot else going on. There are ferries regularly crossing the harbour to Toronto.

So, to recap:
Foggy Hogtown Boys at the Brunswick House on Saturday afternoons

Crazy Strings, at Silver Dollar, Wednesday nites

Flying Cloud Folk Club, Sunday nites (Google their webpage and then call their hotline and leave a message for perhaps some contacts/info on the scene from Steve of Flying Cloud)

Old Time Jam 2nd Sunday (call Steve Cooper for info.. he lives on Toronto Island.. not hard to find him I suspect given the population there)

And when your friend gets here, if she can post "I am here" and a phone number to MudCat, perhaps a person or few might be able to provide current info of the moment.
