Pros:
Concrete tees.
Multiple ways of throwing (right, Left, straight, through woods, over water). Must be able to do more then straight throws to succeed on this course. Pro shop is open during decent hours. They have discs, snacks and drinks. And there are various bathrooms to use.
Cons:
Tee signs are old.
The so called stream that effects several of the front nine ( #2,3, sometimes 4,and 7 ) is a nightmare. Why, MUCK, MUCK, MUCK. Yes it is a long narrow water way, but if your disc lands in it, might as well kiss it good bye. It will sink and get lost in the MUCK. If you are lucky and are able to remember where your disc goes in and can mark it, the Pro Shop does have a stick to drag the MUCK. So I do my very best to stay away from the MUCK. Also, During rain and after rain, some of the course is "Yucky" to play. But can't blame the course for Mother Nature's actions.
Other Thoughts:
Can't say anything really bad about Barnet, it is the "HOME" field for my family. We even had family BBQs afterwards.
