It’s a one-day show. At top speed, the commute between Dallas and Austin is still over three hours. Highway I-35, the only artery offering a direct route between two cities, has been under perpetual expansion and repair since I first moved to Texas 38 years ago. Oh, and Austinites apparently consider allowing fellow drivers to merge into traffic to be a mortal sin. With all that, not only is the Blood Over Texas Horror For the Holidays show an essential event, but I have only one complaint about it: it’s ONLY a one-day show. Two or three days with the sort of people attracted to a horror-themed gift market? Where do I sign up, and where was this 30 years ago?
