I used to race homers. Try here,
http://www.pigeon.org/ depending on where you are located there should be a link on there to find a local club. Its a blast, I had to give it up because I moved over 100 miles from my club, which raced every saturday from spring till fall. Homers take a lot of patience and a lot of training, which translates into a lot of gas money as you have to take the birds out starting at a mile all the way out to 100 miles to train for races a couple times a week. Older birds can fly 500 miles in a day. I havent got any right now, but if you ask around, someone is always willing to help a beginner.
