From the Urban Dictionary...
a situation in which any problems, difficulties or worries can be avoided
"After members of the staff cashed in their winning lottery ticket, they were suddenly on Easy Street, which enabled them to yell "Screw You!" to their domineering boss and quit their miserable, minimum wage jobs."
While finding some cash might put you on Easy Street, hopefully finding this cache on Easy Street might bring you some luck.
Have Fun and Good Luck!
