Today we launch a summer series here on the Homestretch, introducing you to Calgarians who are passionate about their hobbies. Today we meet a Boler enthusiast. No, not the hat. The tiny trailer! You know, those round fiberglass trailers that were everywhere in the late 60's and 70's. Well, that made-in-Canada Boler celebrates its 50th anniversary this year. And Ian Giles decided to organize a North American festival to celebrate. The Homestretch's Ellis Choe paid a visit to Ian and his beloved Boler, Buttercup.
