There’s always plenty of time for preparation, until there isn’t. This weekend’s Oddities & Curiosities Expo in Dallas’s Fair Park kicks off the Texas Triffid Ranch show season, and that season will be going full-bore until November this year. Come out Saturday from 11 am to 6 pm for the Expo, or come out to the gallery for next weekend’s Manchester United Flower Show on April 6. After that, hang on, because it’s time to get busy.
