Update: The second quarter of 2020 has been extremely difficult for the entire planet. Allow me to add this disheartening news. The owner of the ramp decided it was okay to burn it off for reasons I didn't enquire. The team put in nights and days and tremendous amounts of muscle, brains and redbull in 2016 to build this one of a kind DIY beauty which was safe enough for everyone. After the project was complete we are asked to leave the place and obviously the owner failed to maintain the ramp. 
TopGun was burnt off amidst the silence of this lockdown.
