Show me a wall, and I'll show you a tunnel ! ( I think El Chapo said that ...)
As for CA and the upcoming legalization vote , everyone keeps saying it'll be a slam dunk " yes " , but I'm not so sure it's that easy to predict that outcome ..SoCal is in general very conservative and NorCal is just the opposite , so I think it may be close . I did hear an interesting statistic just this evening ( alleged statistic , so I'll check Snopes ) aserted by the anti legalization movements ; it stated that automobile DUI fatalities in WA and CO , after the pot measure passage , supposedly have more than doubled ! No info on OR yet .
