Flying last week and as usual I set up on the tailgate of my truck then move away to take off. When I was done I wanted to check out another area so I just put the mavic 2 pro and controller on tbe frone seat and drove away. At the next location I realzed I left my bag, spare batterys etc on the tailgate. I rushed back to the other location and it was gone. Basically lost my fly more kit. Case, 2 batterys, gimbal clamp and about 6 nice SD cards. It hurt. Especially the cards. I have since bought another fly more kit and gimbal clamp. My name and address (but not phone number) was in the bag on a copy of my part 107 license. I'm pretty sure someone came by and found it. Hard lesson to learn.
