That is an amazing cost saver! I ran in to someone I went to school with in Cornwall the other day, he complained he couldn't afford to keep his car so wouldn't be able to get a job. I thought about this then mentioned we used to cycle an hour plus to play, he mentioned thats too far.... Amazing, I cycle that some days just because of the fat boy drank too much dog leg I do.
I think we will need to change our attitude towards cars and property unless we want to wreck our greenspace.
