Chemical Warfare Pt.4: Weed patch 2

Behold, most likely the weediest part of my entire lawn... And guess what: It's right in my front yard! Just before I posted this I sprayed all the weeds with broadleaf herbicide, so I can overseed it next month.
Just so you know the brown patches are areas that I "rounded up," so I didn't have to trim them. Other than some powdery mildew I don't seem to have a lot of lawn diseases.









Update on Weedy Patch 1:
As promised here is a picture of my first weed patch, minus the weeds. Over the course of the last month I applied Weed-B-Gon and Grub-Ex, then waited. As before this area is mole haven, now more so than before. I get the feeling that since I killed off the grubs the moles are working overtime looking for food...
Today I overseeded this area with Kentucky Bluegrass and fertilized it with 12-12-12. Hopefully I have better luck here than I did in my burn-down patches (which are growing some sort of "weed" grass)










And just a note about consumer herbicides:
Since my initial interest in lawn improvement I've done a lot of research into herbicide... If you have ANY concerns about the enviroment, public safety and/or your budget, DO NOT buy or use consumer broadleaf herbicides! Most, if not all, contain Dicamba, a chemical which by design does NOT break down in soil! This means that it will leach into the water table, and possibly before that "hit" desirable plants!!! Most also contain Mecopop, which is similarly persistant.
If you're reading this and want to kill the broadleaf weeds in your lawn, go to Tractor Supply or a similar agricultural supply store and buy straight 2,4-D acid. It readily breaks down in soil (with an average half-life of 7 days), and unless it comes into contact with your eyes is more or less harmless to humans and most animals. 2,4-D is also less expensive per application than most weedkillers, and makes good economic sense. Just remember that straight 2,4-D is just that, and does NOT contain a surfactant. I add an ounce of Tide per gallon to my 2,4-D mix; it may smell weird but it does seem to help with the absorbtion of the herbicide.
