To whoever fixed the obstacle on the 276 Intermediate loop - skinny wood ramp up to wide ramp on flat to skinny wood ramp down over a big fallen tree- thanks. Much improved obstacle. Prior to the fix, the skinny ramp up was slanted away from the top, causing rider to slide off if there was any moisture. I'm wiling to help with repairs to the Frick trails at any time. Please post if you are planning to take on any other trail improvements.
