oxygen dilemma!!

Okay ive just decided to go and start looking for a tent for oxygen just to know where to get a good one, some people might think iam a bit early but from my experience of the last two times ive gone to the festival and only being able to get a tent the day before or about two hours before I have to leave. I think tents are like one of those products when you dont need them, there everyone but when you have to get one there nowhere to be found!!!! Definately not getting one out of dunnes no offence to the store but they have crap tents I mean tents are made for outside yet dunnes have decided to sell tents that are not water proof????, now maybe if Ireland was a warm place where its dosent rain this would be acceptable....but its not and at a weekend festival down in the country its is more then likely going to rain!!!
Definately need a good tent going to oxygen. Me and my mate on our first time going to the festival we did go a little unprepared with an extremely small tent that was suppost to fit the two of us and bags and everything and of course the tent leaked but thankfully got most of our stuff out before it got two bad and got to stay in another friends four man tent but another few friends of mine tent flooded i mean stuff was floating it was that bad, so they we all ended up trying to sleep in the same tent so it was about 10 or 11 people in a four man tent. awh well had a good time anyway could hav been worse could hav gone with stephen!!!!
