Performing for near capacity audiences last weekend, the One-Act Play âSister Mary Ignatius Explains it all for Youâ takes a nasty turn as a past student pulls a gun on her old teacher. The dark comedy accompanies âThe Actorâs Nightmareâ this Friday and Saturday at Montanaâs Smokehouse in Avon. Visit vailtheatre.org for more info and to get tickets for this closing weekend before they sell out (youâd be really sad to be turned away at the door!).
