Collingwood St has turned into a race track for the day with handmade speed machines fly down it during this year’s Mike Pero Trolley Derby. Racing kicked off just after 10am this morning and will continue until 4pm today, featuring a recoding number of participants. The event has a total of 92 entries this year from the junior Zoomers to local businesses who will be battling it out for the Monarch of the Hill title this afternoon. All proceeds from today’s event will be going towards local charity Big Brother, Big Sister. Come along and see the thrills and spills for yourself.
