It does not feel like I have been playing all that long to me either. I think I have come a long way since the time I first started though.
The course where the picture was taken is very well kept up. It is hard to lose a disc there but there are a couple of holes near the river where this might happen.
The red tee pads are closest to the basket, followed by the blue being farther back and the gold being the farthest away. I've never played the gold tee pads on this course but it looks like it might be fun sometime. On some of the holes, the red, blue, and gold tee pad is the same.
In general, the red tee pads are the easiest to score well on since they are closer to the basket. This isn't always the case if you are someone who throws a long way and has trouble controlling a touch shot on a shorter hole. The red tee pads on this course have the same par as the longer tee placements so that helps your score a lot.
Sometimes on a course, the shorter tee placements have a different par and it can make things more difficult. I often play on a course where some of the easy par four holes are turned into difficult par three holes on the shorter distance green tee pads. A longer distance throw from the shorter tee pads can easily get lost in the woods and result in a bogey.
