- Drilling holes in the tyre, using a mould. I brings a natural resistance up in me, as this is normally something you do not want to happen!!!
- Special thanks to Daan van Os who made the drawing from the mould
- Special thanks to everyone on the North Pole Ride Supporters flag who made the financial part possible. www.sjaaklucassen.nl/en/category/north-pole/north-pole-support/
