Sailing - now that would be actually be quite useful for crossing the river.
I think boats are quite expensive though, not sure i could afford one.
Hillwalking - I'd have to travel almost 50 miles to find a hill. Why do you think i travel 50 miles to go mtbing...
Bird watching - bit boring after a bit isn't it. Oooh great, another sparrow. oh - what's this one here?! A magpie! Oh, another sparrow there. Blackbird. Crow. Great.
Beachcombing - again, MORE than 50 miles to a beach!
Orienteering - again, largely shoot. Audaxes could be described as orienteering which I already do. As could mtbing. Although again, doens't really make sense, to list that ina list of activities i could do close to home, because by its very nature orienteering is finding your way around an area you don't know - and the closer to home, the more I know the area anyway.
Fishing - don't agree with it, cruel to the fish.
Rowing - again, useful for getting across the river in the morning, but requires a boat which I haven't got and probably couldn't afford.
Tennis: shoot. Normally far too windy in britain. I do however do other racket sports.
Bowling: nobody I know is ever up for doing it.
Diving: too expensive. Have to buy loads of scuba gear and get a padi license etc.
Golf: far too time consuming.
Anyway I don't really beieve you're seriously suggesting I actually give up mtbing and get a different hobby just because it involves a bit of driving.
