Unfortunately, we will be in Missouri at the time, so I hope the camera is working OK.
We are not going to be using welded wire mesh in the slabs as that is rarely placed correctly and seldom does any good wherever it ends up. We are going to use fibermesh (http://www.fibermesh.com/product.aspx?name=Synthetic+Fibers) instead. We used this for our back patio where we live now and there isn't a crack to be found.
Looks like the weather is perfect for concrete placement as well, with temps in the 60's and cloudy weather.
