Poor Las Vegas. Did you know it's one of the largest metro areas in the U.S. not to have its own pro sports team? But feel sorry for the city just yet. With events like NASCAR, boxing, and ultimate fighting, the city has plenty of adrenaline pumping action to keep it warm at night (and bring in boffo revenues).

If you sleep in your Dale Earnhardt Jr. T-shirt or think the 405 is your own personal Indianapolis 500, you'll want to head a few miles outside of town to the Las Vegas Motor Speedway (7000 Las Vegas Blvd. N., Las Vegas, 702-644-4444). This 1200-acre complex boasts multiple tracks that host local drag racing competitions and a few NASCAR tournaments each year. If that's a tad hard core for your taste, there's also a go-kart track and a racing school.

Playing Speedracer is cool and all, but the sport most synonymous with Sin City has got to be boxing (you've seen Rocky IV, haven't you?). The city has been home to many high-profile matches including the recent De La Hoya versus Mayweather bout at the MGM Grand Arena (3799 Las Vegas Blvd. S., Las Vegas, 702-891-7800). The 2007 fight sold $19 million worth of live tickets and a whopping $120 million in Pay-Per-View showings, busting all previous boxing revenue records.

Another sport gaining traction on the Strip is Ultimate Fighting, a mixed-martial art where fighters kick, jab, and grab their opponents in the quest for victory. The Mandalay Bay Events Center (3950 Las Vegas Blvd. S., Las Vegas, 702-632-7777) and the MGM Grand Garden Arena are both good places to catch UFC and MMA title fights. Just be prepared for gore; it may have looked strangely appealing when Brad Pitt threw punches in Fight Club, but the real thing is not nearly as attractive.
