[Tony Curran]

There are just so many lists...

Just for the record, Ottawa is in EASTERN Ontario.

Dave and I held the first EOSCAR group meeting a few months ago. There are
probably 15 S-Cars in our area but only the two of use are active on the
list.

Hey

How come you and Tony are not part of the SOS-list on Yahoo.
(Southern Ontario S-Car List)..

Ottawa is still part of southern Ontario in my books, just like Quebec is
still part of Canada (for now)

Anyways, the link is

http://autos.groups.yahoo.com/group/SOS-cars/

So join up already  ;-)
