Light is the key. I had a great light on that occasion, uh, and extra - some random luck, indeed.
Some people spend weeks
But this is the key, too. The more you explore streets - the more chances you have to stumble upon something intresting, right? But after that it is totally on you: if you could manage to click and catch it or not. I am really glad you like it! It means I nailed it, right?.. - and a !BEER for you.
I would say yes you definitely nailed it! hahahah I agree that some things are left to time and chance, which are afforded to all, but it is what you do with it that counts! Thanks for the brewski browski! =)
