Now that summers come and ive finished my GCSE's im getting out on my bike much more. However there is nothing really for me to ride within a mile or two, which although is not that far, if I want to just got out for half an hour or so, is to far. So basically my question is, is there anything good I can mae in my back yard? It is a reasonable size yard about 15-20m by about 7m. I have a path leading to it so I don't need any room to get my footing etc. I have access to quite a few logs, planks and could probably get hold of some crates. I have already just laid out logs and tried hopping from one to another, however that gets very boring, very quickly as it is so short and not very difficult. So I am more looking for something I could construct which would be good. Any replies would be helpful although please don't just tell me to ride the mile or two to the city centre as I am often left with shorter times in which I have nothing to do and rarely have a whole day free. Thanks
