Not sure you can protest a volcano though

Look, the guys got the right to protest. People protesting the very things that earnt them that very right is not new and it is an Irony often lost on these individuals however im happy that I live in a country where individuals can do these types of things without serious consequence (for alternative see syria). Conversely we have the right to hold and attend an airshow that celebrates all things aviation.
There is no reason as to why these two events will not co-exist quite happiily,as long as the protest is peacful and not disruptive then there is no reason why they cannot. We all know the boys in blue will nip any toruble in the bud before it means they have to do any serious overtime on a weekend and ultimately in a who shouts loudest match the afterburner will always best the hippy

Like mentioned above if the charity is legit I will drop a pound in the guys bucket and then I will proceed to enjoy a weekend that celebrates not mans ability to make war and carnage but our ability to be creative , push boundries , celebrate our past endevours and to simply entertain.
Was once Liveforriat2007 but that wasnt a great year so Ive decided to simply live for RIAT period.
