Ramp-to-ramp jumping on a bike is as roots as it gets and this week's Friday video from Dennis and boys goes pure daredevil when they meet up with the infamous "Kohl from SD". Just remember, not all ideas are good ones.

"I have been wanting to ride @KohlfromSD 's famous DIY ramps at his house for years and we finally made it happen! It was nonstop from beginning to end, and an amazing example of what you can do on a budget. Add Kohl's creative mind, some good friends around, and the session was priceless.

Thank you Kohl for being you!"

Dennis is supported by DIG partners Haro, Odyssey and Vans.
