/diy/ - Do It Yourself

im currently finishing up a documentary project thats been on my plate for about a year and a half and one of the last things i have to shoot is a sequence where a specific symbol is lit on fire. i think getting a couple gallons of rubber cement would be the most cost effective and simple way to draw the symbol on the ground. not sure where im going to shoot it though, been thinking along the lines of vacant parking lots or unused plots of asphalt along a railroad- dont know how to do this with assurance that the cops wont be sicked on me though haha. was curious if anybody had any experience calling around to places like junkyards or private warehouses, to have somebody conduct a controlled burn for 20 minutes or something like that. prospects seem pretty grim, dont think people feel good about having somebody come over to their property and start a fire but idk.
anybody have thoughts?
