DKling-thanks for the response. I lived in Chicago for 10 years, on Huron and Wabash. I really don't miss the wind at all. I do miss the nice people. I used to play Cog Hill, White Pines, Indian Lakes and Kennilworth often. But most of my play was down in Indiana. IMHO, where I live now, Bucks County, Phila, NJ and NY area has some of the most beautiful and difficult courses in the country.
I have learned a lot from the "setup" given I can hit as many balls as I want. I had given thought to installing a simulator, but in reality, it's all about creating shots with feel. With my setup, there is no limit to creating shots except for putting (gasp). This brings me to your point about practice. Sometimes, I will provide my own game simulation, using a scorecard from a recently played course. The club selection, the pause between shots, the target, the stance, the recital, the slope of the fairway and green, and proposed ball flight. Other times, I may hit 20 soft wedges in quick succession, and determine my consistency. I really have no idea what the best methodology is, so I just go with it. Some of the best swing thoughts come from watching others on the Internet. Having the slo-mo playback app on the IPAD, IPOD and IPHONE is priceless.
