I like to get to tourneys early, before player check in is even set up. If I have to drive any length of time, I like to get there even earlier. The later you wait to get there, the more people you will be sharing the practice baskets and close in fairways with.
A bad day on the golf course is better than a good day at work!
i am the same as Olydiscgolf. if the players meeting is at 9:30 then i want to be at the course at 8:00. it gives me time to get warmed up slowly and time to check in. even after the players meeting i will take some warm up drives on the hole that i am starting on before the two minute warning sounds. the more loose and warmed up you are when you start your round the better.
