During the weekend of February 22 â 24, an annual off-road vehicle event called the âSand Dragsâ took place adjacent to Lake Meredith. The event attracted over 8,000 ORV enthusiasts to the Rosita Flats area of the park. During one of the many alcohol violations rangers encountered during the event, a man attempted to evade rangers by running away. After a brief chase, he was taken down with a taser and quickly placed in custody without further incident of injury to himself or to rangers. This was the first time a taser has been used at the park since the program went into effect in October, 2006.
