It's about 1200 green fee, caddy fee and tip 800, minivan and bet 600, so about 2600 baht each time, 3 times a week is the norm so I've updated my calc to 31k a month. That's one reason i stopped doing that.
Instead i play golf on a 9 hole course twice a week 320 baht, so 800 baht a week incl fuel so 3,200 baht a month, a 10th of the cost if i was playing with the golf bars
