Opportunities for upper body workouts in the form of bench cutting and rock armoring. Opportunities for exercising your artistic muscle to close rogue trails and make it appear as if no trail existed.

Please join us for a day of payback for the great trails we get to enjoy. PTAG and Dirty Harrys will be joining forces with as many volunteers as we can get to tidy up the trails at Boyce Park, one of the premier parks in the county parks system. Well known for exciting and extensive “singletrack” trails, this is your chance to help maintain the trails you ride. PTAG, Pittsburgh Trail Advocacy Group, is Pittsburgh’s primary organization for improving the trails in the Pittsburgh area. Working closely with the County Parks, PTAG has been responsible for organizing many, many hours of work in the parks we all love to ride and hike. Your work will be rewarded with a couple of hours of cruising the park with a cookout to follow. See you there!

If you aren’t doing the MS150, you should do this:

Join REI Pittsburgh as we celebrate National Trails Day in Frick Park. To celebrate we will be partnering with the Pittsburgh Trails Advocacy Group (PTAG) and the Nine Mile Run Watershed Association to work on the multi-use trails in the park and a litter sweep of Nine Mile Run.
