3.5 hours spent weedeating? Damn son you've gotta do something to reduce that!
I don't do that every time I mow. The area across the creek takes 2-2.5 hours to do and I only do that 3-4 times a year. The front bank along the road takes 1-1.5 hours and I do that once a month. My regular weedeating only take 30-45 minutes, but I do all the other stuff because of the difference it makes in our place looks. I've busted my ass to reclaim our lot over the past couple of years and its all worth it when I roll out on a morning like this and it looks great!
