New year same place - the Enjoy the Trick Summer Jam
will take place on September 9 at Smith School in Portland, OR: "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".
It's the same day as Voodoo Jam
so you got 2 cool options for that weekend.
