Long but narrow backyard need friendly ldc advice

Check your local regulations to see if you are allowed to shoot an air rifle. From the size of your yard I'm assuming you live in a town or city. For some reason my town allows me to shoot firearms in my back yard but non powder propelled weapons cannot be fired within 500 feet of a residence !!!! Exceptions are allowed for bow and arrow. I'm thinking some council member thought air guns are just toys for children and no one objected. Planning to talk to them soon. 
 
I'm allowed to shoot here. Once had a neighbor who complained he didn't feel safe, call law enforcement, they saw I wasn't even shooting his way talked for a minute and left. He was pure anti gun but has since moved. Anyway thanks for the responses. I hope to make a decision on which one very soon, I only want to buy once. Though I do see one vendor who gives a no questions ask guarantee....
