Nostalgia isn't what it used to be, and neither is the annual Cruizin' with the Oldies car show this weekend.

The hundreds of car show participants and the thousands of spectators eager for some mechanical eye candy need to know a few things to make this a safe and fun event today and Sunday.

Instead of holding today's 11 a.m. to 3 p.m. "cruise in" at Mossholder's Furniture as in years past, show organizers are moving this event several blocks northwest to the former Tripeny Motors building, now known as the Yellowstone Garage at 355 W. Yellowstone.

John Huff, owner of Sound and Cellular Inc., has renovated the Yellowstone Garage and turned it into a gallery of motorbikes and muscle cars.

Huff, other sponsors and the Oil Capitol Auto Club - with the cooperation of the city of Casper -- will block Yellowstone from Ash to Oak streets for participants to show their stuff, he said.

Likewise, Elm Street will be blocked from Yellowstone south to Midwest Avenue for participants, Huff said.

Organizers have not forgotten about the spectators, he said.

Huff encouraged those interested in viewing the cars to park in the lots near Mossholders Furniture at W. Midwest Ave., Elm Street north of Yellowstone to Industrial Avenue, and other lots in the Old Yellowstone District.

But with a very major exception, he said.

Do NOT park in the lots used by patrons of the Fox and Iris movie theaters, he said. The theater owners need to conduct their business without interference, Huff said.

Cruizin' with the Oldies organizers also relocated the evening parade, which historically occurred on East Second Street.

This year, the Platte River Commons will host the parade along the stop-sign- and stop-light-free King Boulevard that bisects the former Amoco refinery site.

Participants will begin gathering at 6 p.m. on the left-hand lanes of the divided, two-lane boulevard, and begin their parade at 7 p.m. by driving in a loop along the mile-long boulevard from Poplar Street to 13th Street.

Spectators have several options for parking and watching.

They can arrive early, drive in the right hand lanes of King Boulevard, and park in most of the lots other than an area reserved for the golf course and clubhouse.

They also can drive to and park on the large grassy area on the north side of King Boulevard that faces the original Amoco Administration building.

Spectators also are encouraged to park on the north side of the river near the old pump house and cross the river on the footbridge to the Platte River Commons. Parking here will give spectators an easy exit along First Street after the parade.

While some may choose to park on the side streets south and east of the Platte River Commons, parade organizers and the management of the Three Crowns Golf Course said spectators should not walk on the greens.

The final major change to this year's Cruizin with the Oldies happens with the relocation of the "show and shine" from 9 a.m. to 3 p.m. from Fort Caspar to the Natrona County Fairgrounds.

Unlike Fort Caspar, with only one entrance, the fairgrounds has several ways for spectators to gain access to the show.
