A slang expression? "We were hanging pretty heavy in Seattle"

[Emmaprad]

Hi everybody,
Could someone help me to understand this expression?
"We were hanging pretty heavy in Seattle"
Is it a slang expression?
The context it's about Seventies, after political activism years. The persons in question drink a lot.
Thank you for helping me.

We were idling, lingering, partying, rocking .... (i.e. doing nothing, relaxing)

It could be in reference to spending a large amount of time with one or more people. Meaning: close relationship or friendship, hanging out quite often.

It could also be referring to spending a large amount of time IN Seattle in addition to the refernce to other people.

I think it means that they were doing something important. What they were doing had meaning. They were having an impact.
