For newlyweds Harrison Ford and Calista Flockhart, the honeymoon will have to wait.
After marrying in New Mexico on June 15, the couple stayed put so Ford could resume work on his upcoming film Cowboys and Aliens.
“It’s business as usual as far as I can tell,” a source tells PEOPLE, adding that there have been no congratulatory cakes or speeches for the couple. “A lot of people still don’t even know about [the wedding] on the set out here.”
The source notes that the location – a small town outside of Santa Fe – isn’t exactly a romantic hot spot.
“It’s hard up here,” says the source. “There are mosquitoes, and then it’s been hard to get used to the altitude. It s really quiet here.”
Perhaps that quiet is just what the famous newlyweds wanted most.
