Last year alone from June to September ,2 or 3 days a week, large bucket or if i feel like it 2 large in one day of 110 golf balls.The range had a discount if you buy a certain amount of buckets and the owner would allow me free buckets that some golfers didn't finish, so everything even out with the money term "you get what you pay for".I would say I hit a total of 10,000 in last two years.After work 2 times a week I walk to a field behind my condo, to develop my my short game for a hour or so.This year finally going to hit the Golf courses.
