People often say that if going to the theater were as easy and informal as going to a movie, they'd do it a lot more often. They have this idea that they have to book weeks in advance and then dress to the hilt — but that's not the case at Miners Alley in Golden, a friendly, community-spirited and casual theater with a lineup of pretty serious shows. No one's going to glare at you if you wear jeans and want to take your drink into the auditorium.
