While my parents were in town for a visit we thought rather than letting them take one of those desert safari trips that we'd round up the 4x4 crew and head out to Big Red. After about two hours we'd made our way fairly far north and up past fossil rock we came across the biggest dune I've ever seen - probably about 7 stories tall, this thing makes Big Red seem like an anthill. Me trusty V8 couldn't even get up half way.
We named it Mega Dune.
