The only real option, if you want a dense stand of turf, considering all the wear/traffic is to cut down some trees and use bermudagrass. Bermudagrass is most aggressive and wear/traffic tolerant turfgrass. You will also have to maintain the bermuda at a high level. This means core aerification a couple of times during the growing season and keeping the fertility relatively high. The other turfgrasses mentioned, St. Augustine will not hold up to concentrated traffic, fine fescue will never hold up to the traffic, zoysia is a slow grower and probably won't be able to recover fast enough. Tall fescue maybe an option it will most likely look terrible by the end of the summer, but if you can keep the boys off the lawn for three weeks in the early fall. You can reseed the worn areas and anything that gets taken out by disease and have your yard looking good by the end of the fall. Just read your last post jdawg, the reason why fescue is not ideal is the amount of traffic your yard is getting. Tall fescue is a cool season bunch type grass. That means when you lose some grass from traffic or disease the tall fescue is not going to fill in the area, and over time that leads to bare ground.

They're all just guessing without a load calc, which is sometimes hard to get done. 3 tons sounds crazy for just over 1000 sqft, but only a load calc will tell for sure. The old ducts probably need plenty of attention to get get the airflow needed for the new system. That's step 1.

Are any species of the shingle mushroom in the first pic edible? Just discovered recently that Amanita muscaria is quite delicious, if you don't mind the very,very,mild,harmless, entheogenic side effects. Too much is not good though! The rain can wash off the white spots, causing people to mistake it for the other edible Amanitas, but historically speaking there have been no reported deaths from its consumtion in over 100 years.

Hot Prince is a creation of Hot Princess (one of the best hot house roses to ever escape into the everyday garden) and Gemini. Like it's parents, it carries a nice mild scent. I like the bush habit better then either parents. Not tall and leggy. More rounded and nice and bushy. The blooms seem to glow from the inside and hold well on the bush and in a vase.
