In all honesty, it's the best. The freedom is just unimaginable and there is a no doubt adrenaline drip effect. Continuous higher awareness of your surroundings and conditions. You can SMELL the world around you!
It's completely do able. I recommend a beginners riding course highly. They will give you enough skills to stay alive until you really learn to ride.
There is a 'danger' aspect that a rider has to deal with. Not forget, and not discard, but learn to dance with. It's probably the thing that stops most people and it is clearly a factor in the end of a riding career. But it's so rewarding!
Definitely. I would never jump over before having some courses first :) Thanks for the advice!
