Places like the LZ in Eastern Ontario already have what you are looking for.
In Toronto.. Access to decommissioned Schools is nailed down. There are games weekly in such facilities here in Toronto.
Access to th decommissioned Prince Edward Heights Psychiatric Facility in Picton is also possible, with diligent effort.
You guys are sitting around talking wistfully about stuff that other people have already done and are doing.. Every week
