One thing I am looking to do is grab some audio and video with allotment gardeners in the UK. I hear so much about allotments and the various reasons people garden there and I want to take some time to talk with them and get their thoughts and advice.
I am scanning the maps and satellite pictures of the UK cities we are visiting and think I have found several allotments. Now I just need to take the time to go there and see what is happening. If you have any advice on places I might visit, please pass along a note in the comments.
