@JetCat Life is tough. but Its tougher when You're stupid. ( not you )
Too many peeps are afraid of their own shadows. Here is my experience.
23 years ago I built a shed. I wanted it to last and not rot. I used ALL pressure treated wood on it. Floor is cement. Guess what ??????? it did not rot at all. Other items on grounds not made of treated lumber already rotted and crumbled.
I enter shed at will and only thing that happened to me during these 23 years. is
1. I became 23 years older.
2. I slightly gained weight....
Now lets look at what most decks are constructed of..
1. Cedar,, If you have the cash
2. Plastic recycled things that resemble boards.
3. Treated decking and railings. I see families with children enjoying their decks all over this nation. I also see seasoned citizens sitting around enjoying beverages and whatever else on their decks. I do not see warnings against using backyard decks. MUST NOT BE THAT DANGEROUS.
