I just started playing golf about three months ago and love it. Bought my first set of clubs the other day and can't wait to get them out to the range.

My question is about the "other" stuff that goes along with golf.
For instance, I notice that pro Golfers wear one glove. Why not two? And what hand do the wear it on? There off hand or strong hand?

And what about golf shoes. Are they really neccessary of just something to make you buy more stuff.

I also notice that most people dont have all the clubs and irons and so forth of the same brand. Why is this?

Any help on these topics would be greatly appreciated. Thanks.
