Is this about a big fire, or a fire?
You can't condone fires this size but the fact is, when kids and louts see a fire they want it bigger. These people have no right to be given the privilige(in Scotland) to see our ruggedside, much less to enjoy it.
I like a campfire, I keep it small and maintained and care is taken where it is sited. Fires like mine are fine in my opinion and are surely the basis of human survival. I can't see how anyone can have a problem with that.
Minimilist camping is something us kayakers take seriously. I don't think kayakers would do this as we all share the same respect for the enviroment.
In perspective though, what does it take to make our kayaks? Our cars to get us to launch? The tins of gas we want to blow these ppl up with? Our simple and light-weight food we want to take with us? Can't be many kayakers shooting wild deer out there.
You could play the enviromentalist line right back to when we were amobeas, but the b*sr*rds who did this fire shouldn't have been there in the first place. Probably jet-skers :).
