I did my first official trail work in support of getting the Los Padres reopened after the January rains and cant recommend it more.
The scenery was at peak green and flower cover which was nice, and being back in the closed area for the first time since last year was also nice, but the best part was the people. I thoroughly enjoyed everyone on the trip and made several new friends in the area to hike with. (and I am picky about who I enjoy, so for everyone to be great is truly exceptional and is a testament to good people coming out to clear trail)
You will work your ass off, but it will feel good, be fun, and make lasting friends. I highly recommend everyone volunteer for a Working Vacation! You can sign up with your local forest conservation group, in my case, the Los Padres Forest Association. (and for anyone in the SoCal area, there is another cleanup at Piedra Blanca May 17-22. Please join us! Sign up at lpforest.org)
