Out and About in LasVegas

What to do After the Convention

While Las Vegas is known for the casinos, lavish hotels and stageshows, there are other activities if you have some time.

Located in the Toiyabe National Forest, Mt. Charlestonis nearly 12,000 feet tall. A distinct departure from the aridlandscape of Las Vegas, the area has an average temperature that isabout 20 degrees cooler. Northwest of Las Veags by about 25 miles, Mt.Charleston has ski runs during snow season, campgrounds and hikingtrails. Activities include hiking, biking, camping and horsebackriding. Entry to the park is free.

Located 15 minutes off the strip, the Las Vegas Mini Gran Prix has thelongest go-kart track in the state. An electronic, 10-position timingboard compares lap times to establish bragging rights. The track isopen from 10 a.m. to 10 p.m. daily and until 11 p.m. Friday andSaturday. The track is located at 1401 N. Rainbow Blvd.

Located 17 miles west of the Strip on Mount Charleston Blvd., Red RockCanyon receives nearly 1.2 million visitors every year. Anever-changing panorama of multi-colored hills marks this naturalwonder. As the sun moves across the sky, the light changes, and so toodo the colors of Red Rock Canyon. View petrified sand dunes, waterfallsand red-tailed hawks circling above. The 197,000 acre area provides a13-mile scenic drive, more than 30 miles of hiking trails, picnicareas, and a visitors center with exhibit rooms and a book store.

Getting Around in LasVegas

You may have noticed that construction of a monorail system hadbegun at NAB2003. The Las Vegas Monorail is due to begin service thismonth, which means it will be fully ready for the NAB conventioncrowd.

The Monorail runs from the MGM to the Hilton along a route that followsthe Strip and then cuts over to Paradise Road. There are Monorail stopsat many of the main hotels and the Las Vegas Convention Center.

This should provide a faster route than the convention shuttle busesand taxis. A single trip costs $3 with discounts for multiple-ridetickets.
