I'm assuming that Strangers and Places (S&P hereafter)count as existing faceup Adventure Cards on a space? So for example, the Witch sitting in some Fields would mean that you don't draw a card for that space for the rest of the game?
And when an S&P is on a Draw 3 cards space, do you encounter the space first and draw before visiting the S&P (as per the rule about faceup creatures on space with Strangers or Places) or do you do the S&P first?
