Well, I zip-tied a roll of chicken wire across the top, covering the entire exposed surface. If she gets through that, I'm gonna start a road show with "The Houdini Softshell"...
I'm currently searching for a pond liner or rubbermaid tub that I can bury in the ground for a permanent pond. I found a tub for $150 on craigslist that is probably 2' deep by 8' across, but the guy hasn't answered my email yet. I figure if I buried that, it ought to last it a while.
How long do you think this current setup (the ghetto kiddie pool pond) will last her? I'd really like to have a good in-ground pound set up asap, but I need to know how soon that needs to be.
