On the list of things we need to get (including a track power meter and some bumper plates) was a megaphone.  We used to use the Blackburn one at Spin sessions, but it's missing or broken or both so we needed to get one.  Especially with the Deakin lads with wind trainers, it's very very noisy at spin when the sprint is on.  Nath and I were reduced to a scraping whisper at the end of last week's spin session.  Not any more!
