Hey M.,
I am also from White Lake and had my yard completely trashed by the same storm. My son's birthday was June 21st and mine on the 22nd. We went ahead and did a party in our yard anyway. Tree stumps, log piles and all. We didn't even have a patio set or play structure anymore, but we had a blast. I borrowed a moon bounce from a neighbor, we did water balloons, slip n slide and had a great time. I had my family bring card tables and chairs and everyone brought a dish. I even thought about making it a picnic style. Or, a cool idea would be an evening party with a bonfire so you could do dogs and marshmallows and they could play hide n seek in the dark. I really wouldn't worry about the shape of your yard. Everyone knows what happened here and they will understand. We had 9 70 foot trees fall in our backyard. Just make the most of it. I love at home parties the best. Good Luck.
