There variables but for me I like to find Free at dumpsters at locations of the sale of items you want
but eventually they dry up , go out of business or finally a worker sees your activity's
for a few years and decides to discover why you do it , I've seen it dry up fast never to have a good
item out one day & soon enough you realize No More
Vacuum sales stores were great for about 8 years but I don't see any out Any More for the last 2 years
utility company's used to never bother me then in time the scrap yard has an actual container there
so that's off limits.
Construction sights can be good .
Old tube TV's seem forever but they will stop some day , leaving Flats next, not really my thing .
I'm in a unique situation I generally had to stop collecting , I am booming full
