There are a lot more normal people than weirdos. At school time, near the school there will be lots of nomal parents and kids. A child over 7 should be ok (depending on the chilld) to walk to school on a well travelled route with no road to cross. When my third child was born my older 2 were 8 and 5, the youngest was ill and i couldn't bring her outside so the older 2 had to walk to school, 10 minute walk, one road to cross. Lots of other kids were walking and parents driving. I metioned to a few other parents that my kids would be walking on their own and they were more than happy to keep an eye out. They are now teenagers and wouldn't dream that a lift to school would be a possibility (20 min walk). Kids need a bit of freedom, if they are always watched they will grow up expecting there to be someone else responsible for them at all times and not be willing to take responsibilty for themselves.
