I live in southwestern ohio, and I think our yard is at the point where it just needs to be re-done. It is overrun with moss and has very little grass. We had very big shady trees, along with a lot of foot traffic from when I was younger, and most of the grass near our house was killed. We have since trimmed the trees and the foot traffic is a lot less, but now there is just dirt in that section, but most of it has been washed away by rain over the years. So I was planning on taking a soil test thing and then rent a tiller and till up the yard. Then buy a load of topsoil and add some compost and maybe some fertilizer to adjust the ph after the soil test. Then till all that in, spread seed, and then cover with straw. I don't know if this is the best thing or not, and if it is, I need some help choosing a grass seed. Thanks I will try and post some pictures later.
