"The 2017 Enjoy the Trick Summer Jam will be September 9th at Smith School in Portland, OR. It’s the same spot we rode last year and you can find directions here. Family and dog friendly; there’s even a park for the kids.
Riding will start at around 11am, and will be followed by a BBQ and gathering at Scott Hagnas’ house nearby. Flatland vids and festivities ’til late, and you are welcome to sleep over."
