I appreciate that its dark at nights, I live in Scotland!!! I mean whenever you get a chance. Its never a bad idea to practice on a nice carpet at home but dont practice longer than 6 feet indoors.

Any distances is good although i wouold check the average size of the greens at your course and dont practice any putts longer tah you will find out on the course. Work from 20 feet to 30 feet to 40 feet and so on.

Good Luck.
