According to Australian scientists, the smell of freshly mowed grass is relaxing and good for people. They're even making a cologne mimicking that scent. Check out the article.
Speaking of grass, according to Paul Azinger, Captain of last year's victorious American Ryder Cup team, he doesn't understand why more professional players don't still wear metal spikes. Tiger and Phil still do, which should tell us something, but we can't since most courses that we play require that we wear soft spikes.
Finally, fall is soon on its way, which means a change in our weather. Play more and play often, even if it means only getting out for nine holes!
