Want to Practise Your Press Release?

I know a few writers have tried crafting a press release about one of their books, with variable and typically under-whelming success. But perhaps if we got a little better at there things, and were willing to aim for smaller, local media and make it interesting to them, press releases would work more often?
All in all I am curious to see your press releases if you have them. So how about sending them along (
ERECmail at gmail.com). If I like them I will blog about the book and post a cover spot in the sidebar. (After all, what are blogs but the very small press!):)
Are many writers trying this approach? Any success stories, tip, tricks or advice?
