Cleverly costumed canines march the parade route – with Santa in the lead carrying a giant bone -- to celebrate the holiday season. Spectators are invited to line the parade route for a barking good time.

Reindog Parade advance registration is $14 per dog. Parade day registration is $19 per dog. Parking is $15. Reindog registration forms, complete with the dog-gone rules, can be picked up at the Information Desk at the Visitor Center.

From Nov. 23 through Jan. 7, 2008, The Chicago Botanic Garden will be transformed into a winter wonderland featuring twinkling lights and beautiful holiday horticulture displays. Outdoors, the garden grounds are transformed into a grand winter wonderland of trees and shrubs dramatically-lit with over 750,000 white lights. A 40-foot tree, lit with LED lights, stands stately on the Esplanade surrounded by large spheres, also lit with LED lights, that appear to be ornaments fallen from the tree.

Indoors, visitors will enjoy lush displays of topiaries, poinsettias and orchids in the greenhouses, and trees decorated by local designers and retailers. In a 10,000-square-foot magical horticultural exhibit, garden-scale trains will wind their way over bridges, under trestles, past waterfalls and through more than 80 miniature versions of Chicago's favorite landmarks. Buildings, tunnels and bridges are intricately hand crafted with natural materials, including twigs, bark, leaves, acorns and pebbles. The Krehbiel Gallery has been transformed into an English country train platform. New this year is a slideshow of exhibit designer Paul Busse and his crew creating Wonderland Express in their Kentucky workshop. -- www.chicagobotanic.org
