Fruit trees (or Claire has lost her mind)

I’m still up because I’m all excited about cutting down the Bradford Pear in our front yard and replacing it with fruit-bearing trees. I’ve actually diagrammed the yard with the deck we want and other structures plus our raised beds and 8 fruit-bearing trees (dwarf) in the front yard. So check it out and let me know if I’m a nut. The trees I want apparently all need pollinators, so that means I must have 2 of each type of fruit (not necessarily the same exact flavor). I did find you can get trees for very little from http://www.arborday.org.
