Many of you who know me will know I'm constantly moaning about house prices, property ladders and the cost of London living... Well, some folk out there aren't as lucky me and the majority of us in this city, who enjoy a comfortable, safe roof over our heads every night. Some people have to make ends meet by living in dangerous, cramp and unfit properties. Some don't have a home at all.

Homelessness and it's causes are a very real and truly tragic problem in London, as well as the rest of the country. Everyone has the right to a safe, secure and affordable home, and that's exactly what Shelter are fighting for, and it's something I feel very passionate about.

On Friday 8th April I'll be attempting to travel round the entire London Underground network in a day. That's all 270 stations from Aldgate to Amersham, Edgware to Epping, Upminster to Uxbridge. The lot!

I'd love for you to join me on my journey by contributing whatever you can, even if it's just a couple of quid - it all adds up! Please help me give something back to those who have fallen on hard times.

Follow my progress here, on my blog @ www.CallingAllStations.co.uk and by searching #WalkTheTube on The Twitters.

Thanks for stopping by :-)
