Re: most amount of $ you've found and where?
I've never found a significant amount of cash. I have however lost cash multiple times. I am very careless at times and even losing 5 dollars is a sick feeling. I lost $1,200 in hundred dollar bills last year. Some rich white asshole probably stole it.
At the same token Ive dropped money at casinos and had it returned to me. I also left my wallet with over 500 cash, credit cards, etc. in a field and a mexican laborer found it, called me, and returned it to me completely in tact. I tried to give him 20 bucks but he refused.
Long story short if someone loses money that you happen to come across do the right thing and return it, to me.
