In cooperation with the 36th annual Riverfest, the Museum of Discovery, 500 President Clinton Ave., and Clinton Presidential Center, 1200 President Clinton Ave., are offering visitors special deals this Memorial Day Weekend.

Both major River Market attractions will offer $5 admission all weekend -- Friday-Monday (May 24-27) for the Clinton Center and Saturday-Monday, (May 25-27) for the museum, which will be closed Friday, May 24.

Also, for Clinton Center, Clinton Museum Store and Museum of Discovery patrons not attending Riverfest, there will be free parking and a free round-trip shuttle from the designed lot located between 4th and 5th streets and Collins Street to each of the attractions.

Besides $5 admission, which equals half-price for adults and $3 off for children, the museum is offering special programs at the museum throughout the holiday weekend to give people even more reason to visit. Museum educators also will be on-site at Riverfest doing hands-on "tinkering" activities with festival-goers at the Deltic Timber Kidzone Area from 11 a.m. to 8 p.m. Saturday (May 25) and from 1 to 8 p.m. Sunday (May 26).

In addition to engaging with the 85 hands-on, interactive exhibits, museum visitors on Memorial Day Weekend will be treated to a full schedule of special programs, with "The Electric Show," "Awesome Science" and "Meet the Museum Animals" being presented in rotation, on the hour, from noon until 4 p.m. Saturday; 1 to 5 p.m. Sunday; and 11 a.m. to 4 p.m. Monday (May 27)
