The tool that i have been using allot is the weed wacker. The purpose of this tool is to clear trails that are over grown. What I have learned so far about the weed wacker is that it is allot easier to use a weed wacker than hand weeding. I am manly using the week wacker for clearing along the side of walking paths. This tool helps me because I do not have to bend over every minute and hand weed it makes it allot easier on me and it helps me get my job done faster. There is allot of poison ivy and there is also poison ivy at many other National Parks not just Minuteman. Hope every one is having a good summer.
