Window shopping is very depressing and only shows your children what they could have that all their friends do have.
We have no woods within walking distance of our house. Without working we wouldn't be able to afford the bus. Or the picnic for the woods. Tins of value beans are not nice when they're cold, but far cheaper than picnic food.
We have a stream, but I live in a deprived area, it's full of old buggies and nappy bags. It would not be safe for my children to mess in.
There is a park, yes, but there's only so many days you can play in the park before it becomes boring. Plus again, I live in a deprived area, our park is vandalised often and full of smashed beer bottles. The nice park is bus ride away. If I'm not working I can't afford to take the bus to the park daily.
Sure Start in our area has been cut right back. Free swimming has been scrapped. Playgoups etc. all cost money, not much money, but a loaf of breads worth at least.
I have no idea what geocaching is, but they probably don't have it around here.
