Man ends 20-year Llandegley airport sign joke that cost £25k
This reads like a justification for trolling.  "Nobody's hurt and it's all in good fun.  My fun and my friends' fun, that is."Putting up a fake sign is like dropping a single piece of litter.  It's not going to do much by itself, it's just a tiny bit of pollution which makes signs a tiny bit less useful to the general public.
