So far those dates are good for me!
In terms of ideas:
Lower Don Valley/Riverdale, if nature photography is of interest
If people are interested in working with a model I am sure I could arrange something (I've been working wiith a number of Model Mayhem models recently). I could provide basic studio lighting and wireless triggers (Cactus 5) but we would need to find an interior space to work with (my home studio is not really big enough for this kind of event)
U of T - some interesting buildings there (e.g. University college) plus plenty of pubs/resturants, easy to get to on TTC.
