As for myself, I will be running Labyrinth Lord at the Con again this year, very likely using a homebrewed adventure called Keep of the Zombie Master. I will keep you posted on my own plans for OSRCon here at the Lands of Ara blog.
OSRCon registration only costs $20 CDN before July 1st, or $25 CDN afterward, so make your plans and register soon! Also, keep an eye on the official OSRCon website and blog for updates about the Con, the gaming schedule, etc.
I hope to see everybody in Toronto in August!
