NBR: Anyone put up a fence?

Telyco

Well - I guess it's sort of baby-related.

We need to fence off part of our backyard. Most of our yard is to the side and front, but there is plenty in back for the kids to play and keep busy - including some pretty cool woods. But Evan loves to run around the house and has tried to run to the street a few times so we need something to contain them....esp for when Leah starts running away too

The trouble is - we don't really want anything super permanent/expensive because it won't be there forever. I don't think our neighbors would like orange snow fencing...so I gotta find something else.

Any tips would be appreciated! TIA!
