For a total change of pace, let's meet at Isles Bun and Coffee, where we'd have the choice to order a Cuppa--or not, and then the option to chat awhile there or go directly on a walk around Lake of the Isles.
From the café and back around the lake, Google Maps shows it is just over a one-hour walk. Chatting beforehand at the coffee shop or somewhere by the lake, if we stop, could bring the event to about 90-120 minutes depending.
(Option: If anyone votes for biking this route, we could do that, too.)
