HEY!
Well me and my friends used to be into parkour, and there are LOADS of places you can go. We live near Doha College, and there were loads of construction sites going up around the place, so those were great places to practice. Some compounds can also be great places to practice.
To be honest, Free Running may be easier cause it's a lot more fun to race your friends from a place to another using shortcuts over walls and over objects etc.
