It's not smart to poison the pond you plan to fish in later.

"Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime."  

There is amazing fishing, outdoor recreation, national parks, etc. all within reasonable driving distances.

I'm old, have family obligations, real estate, fishing holes, and friends so i'll just compete from afar with my " team " 

There are no amenities such as fishing, laundry, showers, rec areas, etc, just pads approx 30x60, an electric pedestal, and water, with crushed rock.I have an idea to put some RV pads on the land I bought and rent them out.

Fish can cause water damage if the tank leaks or breaks.

A little to filling, also you could mix it up and change sauces or cook in fish or a type of meat or veggies. 10 pounds of rice will run you about what you'd pay for one day's worth of lunch and will probably last you a year.Also many banks offer a brokerage service, at least with wellsfargo they have a money market account that is highly liquid, i can get cash from it in ~2-3 days, and it pays monthly interest at a 4.65% APR.

On the other hand I have a friend that has a wife of 60+ years, a paid for home, kids and grand kids that visit him all the time, hunts and fishes whenever he wants, never made more than $40K a year and doesn't really want for anything.

I have bought and sold everything from high end imported automobiles to a veterinary hospital to fishing gear and fishing boats.  

Nicer fishing there too.
