The need to be the very best is perhaps bringing out the worst in some Pokemon Go players.

Arlington National Cemetery is the latest place of reflection to request that visitors stop trying to collect Pokemon on their grounds.

We do not consider playing “Pokemon Go” to be appropriate decorum on the grounds of ANC. We ask all visitors to refrain from such activity.

People on Twitter are reporting PokeStops within the cemetery, including at the grave of civil rights activist Medgar Evers.

This follows D.C.’s Holocaust Museum, which called playing the app inside the memorial “inappropriate,” as well as requests from National Mall and Memorial Parks authorities for players to be a little more sensitive around memorials: “Yes, it might be tempting to go after that Snorlax near the Vietnam Veterans Memorial, or the Venusaur hanging out in the chamber of the Jefferson Memorial, but remember that there are places of solemn reflection here at the National Mall where playing Pokemon just isn’t appropriate.”
