I have extreme respect for engineering.
I've always played around with things like bridge building simulators, but it isn't even close to the real-world situations you face.
I appreciate you detailing the steps and giving us some insight into how that world works.
Like they say, you're paid to know where and what to build - and its worth every bit.
It is my pleasure to introduce other people into the basics of engineering and to show my modest knowledge, and I am very pleased that you like my work.
