Leave US with ESTA

I’m from Germany and I have an approved ESTA. I already bought flights to the US and back and I’m staying for 6 weeks. But now I’m thinking about spending around two weeks in Peru. Would it be possible to leave the US to Peru and return to the US after a few weeks with my ESTA?

How long is it safe to leave marker on a Chessex battle map?

I have a Chessex battlemap and it’s been working great. Sometimes, though, I want to prepare maps in advance to save time during the session. However, I know that marker left on the mat for too long it will become permanent.

If I prepare my map 6-7 hours before using it, will it stain? How long is safe to leave marker on the mat?
