A few corrections.
The link wasn't working. I've now fixed it.
The kids weren't walking home from school but rather the park.
Now that I've got that out of the way. yes distances are a long way for kids. But so what. Weldon and I rode our bikes to school. I think we started in 2nd grade. Maybe it was 3rd? It was 0.80 of a mile. Yes I had someone with me and we met our friends at the end of the street but in 2nd grade we'd be what 8 and 9 in third grade.
Now clearly weldon and myself are geniuses but it didn't seem to be too big of a deal.
