My BFF and I used to roller skate in a cemetery as kids (there were no paved sidewalk in our neighborhood but there were in the cemetery).  I would not recommend anyone do it though. Walking is fine.

I used to rollerblade in the cemetery too! I’ve never talked to anyone else who did the same + thought I was alone!
