I'm taking on the challenge of traveling all 11 lines of the London Underground, covering 250 miles and going through all 272 stations. This incredible journey will take approximately 17 hours of travel time over two days to complete. I'm doing this to raise money for the World Wildlife Fund, an amazing organisation that works to protect endangered species and their habitats around the world. I have always loved trains and the environment is very important to me so I thought that maybe I should combine the two and do a charitable fund for this and for my bar mitzvah. Every little bit helps, so please consider donating to this important cause.
