What happened? You made your perfect swing.
It happens to me every so often, especially with irons. It's almost always when I'm making a smooth 3/4 swing. Perfect everything(for me) and the ball may carry 15 yards farther than a normal shot.
Happened to me yesterday with my gap wedge(110) carried 120 or so.....led to a double bogey.
Could be a number of things;
Weather can affect how far a ball travels
Your irons could have a hot spot that you don't typically hit
As @Grinde6said you could have compressed the ball a bit more than usual or delofted the club.
Could have been the lie that caused a flier.
In this case enjoy it since it worked out well, sometimes these happen on approach shots and you end up flying the green which aren't as enjoyable.
Do you not think that some people are turned away from being interested in golf because their opinion (regardless of the fact that no... it's not true, but again, the outsiders perception) is that a lot of "golf clubs" are like Augusta with their strict rules and funny ways they make you dress as outlined in this thread here? I mean c'mon... mandating the colors of your socks and belt? Pure stupid. Nowhere did I say jeans and a t-shirt should be considered acceptable everywhere and I even said how I dress on a course - pants and a polo shirt tucked in. My comment is that even that seems unacceptable at the courses that people are posting ridiculous dress codes for. When I say snobby or elitist for golf I am referring to those courses like Augusta, just because it is so famous doesn't mean there aren't plenty of private clubs like it. Yes, they are snobby, elitist "rich guys stuff clubs". Those clubs don't grow the game in any way shape or form, and a non-golfers perspective is that a lot of courses are like that, it keeps them away from golf. My friends who don't play golf think that way, no matter how much I try to tell them otherwise, this is where I base my opinion.
