See those hills outside? You can ride down them. Hence the term "down" "hill".
Not the same on local hills, just nothing entertaining about it – I never felt that I was close to "the edge" with stacks of travel. I just got bored of it TBH.
Or are you saying that there was nowhere in the UK challenging enough for you on a DH bike, in which case you should turn pro and make a mint from riding DH for a living on the world circuit, you would be the winner.
Nowhere within easy reach, no. I'm sure some of the scottish man-made routes are fairly hardcore but they take too long to get to when you live in NW england and natural trails are hell on a long travel bike as you need to get up the hills first to get back down them. I'm actually fairly sure I could have done quite a good job at competition level DH until they started introducing bigger and bigger doubles jumps (I'm not a fan of doubles, I'm happy with drops and natural trail jumps, but many did suggest it at the time) when I ditched the long travel, on my first runs on a marked DH route in Les Arcs I was making times in the top 1/3-1/2 region when compared against the actual competition day times. Coming home to the UK left about 3 trail centres with anything remotely close in enjoyment stakes and they were impossible to get to and very short run times. I was wholely deflated, this is when I left the sport for a few years (6 or so) and eventually came back more XC oriented.
