Although the trial court held that plaintiff had the right to terminate the lease pursuant to section 10 of the lease, we may affirm on any ground supported by the record, regardless of whether the trial court relied on that ground. See Swilley v. County of Cook, 348 Ill.App.3d 405, 407, 284 Ill.Dec. 514, 810 N.E.2d 167 (2004). ¶ 26 Plaintiff argues that this appeal is moot as the billboard is clearly now illegal since April 9, 2009, has passed.
