When the sun comes up Saturday, plenty of people, animals and contraptions of all sorts will be found assembling on Upper McCulloch Boulevard to step off the 44th London Bridge Days Parade.

The theme of the 2015 edition of the time-tested celebration that rounds out London Bridge Days is “Remembering Havasu’s First Businesses: As the Chamber of Commerce Celebrates 45 Years.”

And many of those businesses will fall along the parade route down McCulloch Boulevard. The parade begins at 10 a.m. Saturday.

In conjunction with and in honor of some of those businesses, the Lake Havasu Museum of History is displaying a special exhibit featuring some of those sustaining businesses that remain viable parts of the community.

The exhibit, “Passing the Test of Time,” includes memorabilia from Ed’s Deli, Havasu Pest Control. Lietz-Fraze Funeral Home, Jet Printing, The Apothecary Shop, Continental Land & Investment Corp., Havasu Hardware, Western Safe & Lock, Larry Lundin DDS, Havasu Lanes, Londonderry Realty and Taco Hacienda. Although some of the businesses featured have changed ownership or have been passed down to family members, each has been in business since the earliest days of the city.

The exhibit will be displayed until mid-November. Take a walk down memory lane and look at some of the economic engines that have driving the community.

The Lake Havasu Museum of History is located at 320 London Bridge Road. Hours of operation are 10 a.m.-4 p.m., Tuesday-Saturday. Admission is $5 for adults. Children under 12 are admitted free.
