It’s too bad that most drive-ins are only open in the summer; otherwise, they’d be the perfect year-round cheap date for the starving — and horny — college student. As it is, only students attending Colorado State University’s summer session get to make out at the Holiday Twin Drive-in. Although the pictures tend toward family fare, the location on the far west side of town gives you a great sunset view of Horsetooth Rock before the show starts.
