Vancouver's other Olympic sport

These two alone on one shift pick up on average 250 needles per day?
This is winter time in Vancouver! Why would people sit in a freezing,
dirty alleyway to shoot up when they could go down the block to a
clean, well-lighted place with professional, tax-paid staff to assist
them? Let me see: cold alleyway on one side, nice warm place around the
corner. Why choose the alleyway. Daily. Why choose the alley 250 times
per day!

And that's just the two pick-up guys in question. There
are other workers on other shifts in other areas. The needles in the
pail tell the story the povertarians won't tell: drug addicts on one
shift in one small area of the city don't use the needle exchange on
average 250 times per day. The needle exchange is as close, at least
often, as around the corner. The drug addicts don't use it. Why not?
It's as simple a matter as staying warm and dry. How bad does it have
to be indoors to drive a junkie into the cold? 250 times per day on one
shift in one area!
