Hi, I have 2 questions for you. 1. I want to build a shed in my backyard that will be like a room, because where I live if it's less than 200 sqft the overall amount of permits I need goes way down. Would you recommend a concrete slab for this or dissing up like a crawlspace area and adding hardwood? If concrete, in general, how much would you say that 200sqft of concrete costs? 2. I don't know a lot about concrete or really building things in general, but is rebar always uses in building a foundation? Just kinda curious.

I live in Seattle, Washington, which has so far been one of the few states to legalize weed, and so my question is if you get weed legalized nationally, how on earth are you planning to stop children from using it? I can't tell you the amount of kids I've seen smoking it, it's insane, and so far nobody has done anything about it.
