The retiring baby boomers like greens and blues for the most part. Greens and blues are great for getting non bikers into the sport and active. They’re might not be so much appetite for reds and blacks that the FC started off with all those yrs ago.
Also, if you think “free” parking is in the NTs business plan you’re prob not on the same page ( I’m sure there are some exceptions in underused car pks in out of the way places). If you think FC trail centres are expensive for parking last time I went to cragside (NT) it cost £27. 50 for me, my wife and our little one to get into the woodlands to use the play parks. If you wanted to access the house as well it was £42 or something.
It’ll cost a family £10 at bedgebury for a whole carful.
Just for disclosures sake I do work for the FC and I am now a NT member (that costs me over a hundred quid a yr!)
