I just realised that maybe one reason I liked Bert from The Fastest Indian so much - he reminds me of my grandfather, Ronald Seabrook.
My mother's father fought in WWI, and among other things, built and rode motorbikes in the local speedways and elsewhere. In fact my aunty Glennis (who died this time last year) met her husband Jack when he was racing at those events as well. Ronald was very clever with his hands and very much a D-I-Y person. He also built my very first push bike from spare parts.
Always loved him.
