So, I was poking about on the Unknown Armies site when I saw that John Tynes and Kennith Hite were involved in this new project called Behemoth3
which includes something called Otherworld Excursions
This is described as a hosted tour around the city involved, with dinner and a game GM'ed by the excursion leader.
The one for Ken Hite (who was the writer of Suppressed Transmission, and a writer on the new GURPS Horror is in Chicago which would be close enough for us to go and spend a day.
It is a little pricey ($175/person) but would be a cool little excursion.
Hit the sites, see what you think...
