Complete with a garb not dissimilar to that of his character in the movie “Caddyshack” — all the way down to the bucket hat — Bill Murray hit the Willis Case Golf Course Friday afternoon to celebrate his 45th reunion at Regis University. Murray, a part of Regis’ class of 1972, typically makes it out to his 5-year reunions, according to Skip Stewart, visual media director for Regis. Denver residents crashed Murray’s party at a bar in LoDo last night and had a chance to meet the comedian.
