...so much for all your information. I can't tell you what a relief it is to hear that asphalt is much easier to remove than concrete. I watched a muscular neighbor struggle with removing a small concrete foundation in his backyard and knew there was no way that I could manage that kind of work. I am sure that I can manage all or part of my asphalt. And I have 3 very able-bodied children that can help :) I will probably leave part of it and pave over it for a patio in the middle of the yard, but at least I know now how to plan. And knowing that it won't cost a fortune to do is a great relief! Thanks again!
