Sand Golfer

Hi,
My name is Keith and I have a 22 handicap. I am different type of golfer in that I play on a sand golf course most of the time because I live in Saudi Arabia. I have access to two grass courses but its a weekend or special occassion to get there. So, the sand course is available everyday. I play off of a astro turf pad and the greens have to swept after each group. Doesn't that sound like fun? I have a love hate relationship with my game. I started playing in college 30 yrs ago and now for the last few years I have been at it again. My hardest shots are on unlevel ground, on hillsides, down hillsides, off of rocks, deep sand, and pitching, chipping, hitting with high wind, club selection from 100 to 150 yds out. I can hit a failrly good drive and 250 yds. I play in regular local tournaments weekly and practice 9 holes 2 to 3 times a week. Hope to gets some good tips. Keith
