I'm somewhat surprised that there are dojos out there that don't teach breakfalls. Probably means I need to get out more.
During our Sunday class, we also run an "ukemi clinic" on part of our mat. I remember one day when I was helping out over in the ukemi clinic that there were two people from another dojo down the road from us who wanted to learn how to breakfall. They knew how to do forward roll and such so I gave them an hour primer.
After class, they said they came up here in hopes of learning how to do breakfalls since they don't teach people how to do that until a certain rank...
