Well what an explore!! I was amazed by the size of this place!! It was awesome!! 
Firstly.. Thanks to Cracking Day most of all! Thanks to Silverhatch for driving and Cogito and his friend coming with us!
We picked up Cogito and his friend from Cosham station and made our way to Portsdown Hill. After arriving we kitted up and shortly we were inside! I didn't realise it was going to be so big!!
We wandered round the whole of the outside corridors first then got out cameras out and started taking photos! It was a morning well spent! After about an hour of being inside (R) Andy and Flat4 appeared and as we were leaving Alias appeared with 3 others! 
I recommend it to anyone but get there quickly!!
