The Tufte family leased a 260-acre farm from the Travelers Insurance Co. Toward the end of the lease, Travelers mailed the Tuftes an option to renew the lease. The option arrived at the Tuftes' house on March 30, and gave them until April 14 to accept. On April 13, the Tuftes signed and mailed their acceptance, which Travelers received on April 19. Travelers claimed there was no lease and attempted to evict the Tuftes from the farm. May they stay?
