A limo may be the gold standard of transportation -- in price as well as prestige. Opt for an equally classy but less costly alternative. Owners of vintage autos are proud to show off their roadsters; an antique auto club might know someone who'll give you to a ride to the reception in exchange for a trip to the buffet table. You might check with the local horse set -- farms, trainers and riding clubs -- for a hobbyist carriage or buggy driver to deliver you for a minimal fee.
If the reception site is on the river or lakeshore, consider a water landing. Gondoliers still ply the waters off New York and California, and in unexpected "ports" like Omaha, Neb., and Stillwater, Minn. Even a pontoon boat festooned with flowers has a certain Greek-goddess appeal.
