In the 60s and 70s the only way to learn, was if someone who knew how to play, thought they could make money off you getting better. That's it, no videos, no books worth reading , nobody would even give you the correct time of day, Those better times is a myth .imo You were welcomed as a new player because you were a potential sucker, nothing else.
This is actually the best time to be in pool since the 1800s.
As someone suggested , you may need to travel a bit, to find the right place to play, but keep trying, and go at different times.
I believe with practice and a little ability , you can learn how to be a semi pro player just from the internet. The info is out there.
It might help if you make friends with a really good player so you can buy him lunch or a beer and ask questions , pool takes at least a couple of years to become decent at, so paying thousands of dollars for lessons, when you are just starting is not the best bang for your buck.
There are so many great players in the Phoenix area, I lived there for about 5 years and went to Kolbys almost every day.
It changed owners a couple of times and now I think the players go to main street, also Bullshooters and Metro are in other ends of town.
There are other people in your situation , maybe ask the house man if anyone there likes to play for fun . Maybe find a place that has a daily special, like from 10 am to 6 Pm for 10 dollars. I haven't been there for 10 years so it might not be available now , but you can ask the other players.
Don't be shy in the pool room or you will get overlooked all day, don't bother someone when they are shooting ,and be respectful of space , but most players don't mind a question or 2 .
I met a lot of nice people out there , I'm sure you will too.
I recommend Grady Matthews kicking videos and Bob Byrnes books Ray Martins 99 critical shots book, Joe Tuckers fractional aiming system and drills. Also watch you tube videos of specific instructions like caroms and banking. I also watched a lot of videos of great players , especially playing nine ball, Practice speed drills , cueball only , and cueball and object ball , learning how far each will travel ,learn the feel of how hard to hit the balls to travel distance x . That is one of the real secrets of the game.
If I were still there I would be happy to help you get started , so I know there are others out there. Good luck!
