Here's a spreadsheet I've been working on with most of the major contests that Texas bands will be attending and the groups confirmed to be going. Feel free to respond with other confirmed attendees that I might have missed.
Also worth noting, I'm only including names that have been 100% confirmed either by public calendar or by other reliable sources. So your super secret calendar people like Flower Mound and Marcus don't have any contests on this sheet even though they are almost 100% going to competitions like BOA San Antonio. I'm not forgetting about them, I just want to keep my speculations minimal and consistent across all groups.
