[Closed] trail centres or out in the open....which is your favourite?

Its all good. By preference big natural trails exploring the wild and beautiful countryside but real life means I don't often have time for that. For practicality, ease and being a known quantity trail centres are great but I wouldn't be inclined to travel far just to ride at a trail centre and would travel far specifically to ride a 'natural' route. But the reality is 99% of my riding is on well trodden 'natural' trails in the local hills as I can ride there from the front door. So convenience trumps everything else for me.
