Gary Allen, a retired emergency medical technician who travelled the world to attend Apple Store openings and created ifoAppleStore, a site dedicated to tracking and reporting on Apple Store opening information that proved invaluable to Mac news sites like MacNN, has died of brain cancer at 67. Allen was an valued source for store opening progress and reports on possible store sites for the past decade, and a former contributor to our sister site AppleInsider. Allen ultimately attended more than 140 Apple Store openings around the world, and made many friends along the way.
