No offense but I think some of you are too quick to say the modern petro stuff won't be collected. There were probably a bunch of guys sitting around 60 years ago that would have laughed if they saw you dragging a Tokheim pump through the streets to take it home, let alone the response if you were to go through their trash looking for quart cans. There are millions of events yet to occur, some of which may vastly alter what people are going to collect. For example, if cars go electric, if alternative fuels come into use, a huge reduction in American corporations etc.. etc.. Whatever causes people to connect with their past is going to be what they collect.
