Mike Cassesso and Mailien Le are scheduled to get hitched at the Jefferson Memorial in Washington, Saturday, the site of their first date.
But with national parks closed because of the government shutdown, the couple is now scrambling to make other plans.
Le says she was alerted Monday morning by an email from the National Park Service saying any permits for events on the Mall would be invalidated if the government did shutdown.
The groom had an ambitious idea.
Cassesso says, "My first idea was to jump the fence and do it anyway but Mailien can't jump a fence in a wedding dress and I don't want to be arrested on my wedding day."
The couple is expecting 130 guests and say they will be moving the ceremony and reception to a local hotel.
