Come buy some. For some reason they can't be sold in weedshops, but they're often next door or across the street. My partner tried mushrooms for the first time recently. The kitties were adorably soft and we just laughed a lot.

Oakland has a fair amount if you're not scared by non-white people. Delicious food, some cool parks, lots of venues. Just don't be wandering in people's neighborhoods causing problems, but thats true for everywhere.
