I can put people up in Toronto (or at the new house depending on timing) while they're not up at the picnic (eg. perhaps the first and/or last night), and can drive a few people up and back.
If the picnic is in Aug you can help me place and calibrate in the wacky triangular "HTIL" (Home Theater In a Loft).
There are a couple of weekends I already have booked, will try to dig up the dates tomorrow.
