Souvenirs, Bongs and Tattoos
Is basically what you're going to find on Hollywood Boulevard and in that order, repeatedly. Plus the locals. Which, I did have some funny and memorable interactions with whilst trying to look at the pavement to read every name of every celebrity deemed worthy enough to earn one - doesn't seem to be that hard... Anyway, but what I wanted to do - and did, but could have more - was to go out at night with all the bright neon lights and all the characters of the night come to life and get some stock of the locale.
