Yeah there are places to train everywhere. You give me an open field and I'm sure I could find someway to train. You just have to open your mind to the possibilities. Look at the trees, tables, and rails. Also as TheSheeve said, playgrounds are really good to train on. You don't even need objects to train. Visualization is a great way to train and get over fear of doing things. There is also conditioning which is a huge part of training. Good luck with your training and don't worry as you get better you will start seeing new things to train on and new ways to train everyday. So have fun and be safe and welcome to the parkour community!
