What I love about mountain biking.....you don't have to don a **** wetsuit/drysuit and look like a navy frogman.....you don't have to go through half a tonne of grades/training.....you don't have to put up with socializing in clubs......and finally you don't need a license to go and ride.....
All you have to do is swing a leg over your bike, stick a helmet on and hit the local trails
It is true, the kit you have to wear to deal with long exposure to cold water and weather can feel a bit restrictive, but thats why kayakers seek out sunnier climes just like bikers where you can wear much less. Besides, if you like kit, its good for that.
You don't have to do any training whatsoever. I've never understood that element in kayakers personally, getting their 'star' grades. Its mostly done by people who want to go on to coach others and need the awards as prerequisites for coaching. I did my two star award many years ago which basically requires you to show that you can forward paddle etc. Never bothered after that.
'Put up' with socialising? Well, some people are more sociable than others for sure. I joined clubs early on and it was a great way to get into what can be a pretty complex and intimidating world as an outsider. I met some fantastic people and have travelled all over the world with my boat. Later on of of course, splinter groups would form and we would go and paddle rivers of our choice, the club becoming just a meeting point or 'hub' for organising trips. I never got involved with my nearest club when I moved, it was pretty much just boat storage.
You do not need a license to go kayaking.
Just as you see there are access disputes for walkers, mountainbikers, climbers and anyone and everyone who uses the countryside, there are continuing disputes for kayakers about access to rivers which technically we only have access to something like 3% of in England and Wales 'legally'...
Its a messy system, an unfair system, largely fuelled by self-interested and self-centred parties (read fishermen/anglers....oops, did I say that out loud?...)
What I love about kayaking each time I go, I don't have to spend ages cleaning my boat.....just shove it in the shed and its good to go.
