While people are posting GC videos... Thought I'd share this one... Damn I'm glad I own a Wrangler
btw, it's a video by the same guy as the ones posted above. I've seen some of his other videos.. Let's just say I could go places this guy only dreams of with my ride in jeep toy I had when I was 6 that had no suspension and an electric motor...
Now back to the intended question of this thread.
Unless you're pretty crafty, homemade snorkels have a high potential for coming out rather.. Ummmm... rough.
