In this weather, I pity the actors in Genesius Guild's production of Macbeth. In addition to the fact they're on stage wearing three layers of clothing and toting swords, shows are performed at Rock Island's Lincoln Park outdoor theatre, which draws little breeze, lots of bugs, and, of course, heat. Though these aren't ideal conditions for actors, or for audience members, people willing to brave the heat for three hours and put on the bug spray will be more than pleased to see an incredibly well-done yet traditional version of one of Shakespeare's great tragedies.
