Well you'd think I was terrible as I take my kids to graveyards on occasion just for a walk. There's a cool one about 100 yards away from the 1700s.
The kids always enjoy it as there's plenty to look at and it's a really handy way of bringing up the subject of dead people and normalising it. We say bye bye to all the nice dead people when we leave.
The one in my hometown is AWESOME cosits huge and the Travellers have these amazing marble graves that are brilliant to see. They're super fancy.
I met someone with a 3 year old recently who has just moved across from my hometown one and everyone was saying how lucky her kid was to have such a lovely big space to explore.
