/diy/ - Do It Yourself

People use this image in a mocking way, but I unironically love it because it reminds me so strongly of my childhood.

It's like when you and your buddies have all turned 11 and your bikes feel too kiddie, so you all start building your own cobbled together mess, splicing in half remembered details about dream cars and duct taping the rest until you have something that will roll down the neighborhood hill, convincing the youngest kid in the group to steer it on the test drive. Sure, it falls apart at the foot of the hill and sure, you got in trouble for the badly skinned knees that your friend got in the crash, but you still have pride in your work because you're 11 and you know that next time, it'll be better.

What's your childhood experience with makeshift vehicles, /diy/?
