Going to the park high sounds boring as all hell. On the other hand some stoned people in the parks might balance out the number of drunk homeless people in the parks.
There is a park a few blocks from me with a specific homeless man that quite literally carries around a machete in a shopping cart.
Oh and thank the not actually real lord it is raining today and I don't have 1,000 little bastards ringing my doorbell for candy. Especially since Halloween fell on a Saturday this year..they'd of been out at 11am if it was nice. It saves me the trouble of telling kids I ate all the candy because I'm high.
