Sturgis Motorcycle RallySturgis, South Dakota

For one week in early August, the town of Sturgis (population 6,400) hosts America's largest motorcycle rally, now attracting well over a half-million people. Begun in 1938 by the local Jackpine Gypsies, the Black Hills Motor Classic grew over the years into a bacchanal drawing gangs of self-styled outlaws. In the late 1980s, the city partnered with the Jackpine Gypsies to civilize the event, and today law and order prevail. Baby strollers are not an uncommon sight--which is not to say that the saloons and tattoo parlors don't still do a brisk business. Wanna-bes and diehards alike partake in the hill climbs and concerts. Downtime is spent admiring each other's bikes, marveling at the Sturgis Motorcycle Museum & Hall of Fame, or eating at the Road Kill Cafe--favorites include Chicken That Didn't Quite Cross the Road and the daily special, Guess That Mess.

Details: Sturgis is 24 miles north of Rapid City. City of Sturgis Rally Department: 605/720-0800, fax 605/720-0801, sturgismotorcyclerally.com/.

Mercado de HechiceriaLa Paz, Bolivia

At La Paz's Witchcraft Market, proud chola women sit among their goods like queens, unfailingly wearing two braids festooned behind them and bowler hats adapted from the British many years ago. What they sell: herbal-tea fusions, folk cures, coca leaves, figurines, snakeskins, slabs of llama lard to be burned in offerings to the gods, and amulets to guarantee a long and happy sex life. The market has lately begun to accommodate the growing number of gringo curiosity seekers, and booths hawking colorful alpaca sweaters and woven textiles do a brisker business than the vendors pushing dried llama fetuses.

Details: Held daily, on Calle Linares between Calle Santa Cruz and Calle Sagárnaga. Best times: April to October.

Diving with Manta raysTobago, Lesser Antilles

Divers are flocking to the island of Tobago for the chance to swim with monster manta rays. A dozen or so giant mantas, 6 to 10 feet wide, live in the Batteaux Bay area, some year-round. Divers may have to settle for a sighting of the creatures, but most will be able to interact with them. The friendly mantas encourage divers to hold on for a ride--a practice that once earned them the nickname Tobago taxis. Today's more-sensitive approach is to merely swim in their presence.

Details: Stay beachside at the Manta Lodge, a dive resort with a PADI facility. Doubles begin at $95 (low season) or $115 (high season); 868/660-5268, fax 868/660-5030, mantalodge.com/.

Best times: November to April.
