I think there must be a wide variation in the nature of Travellers in this country, all the ones around here are nothing but trouble!
as soon as a group turn up in this area Fly tipping and theft go through the roof!
the last ones that arrived close to work ended up with two vans having the Catalytic converters stolen and one of the trucks had an Axe through the fuel tank and the fuel syphoned out all within a couple of days of their arrival, funnily enough crime like this hardly ever happens but it always coincides with the travellers arrival and stops when they go away again.
not to mention the piles of hedge cuttings and rubbish they leave behind.
I have no issue with Gypsies, we have a few in the area, they graze their horses on the verges, have their little camp fires and when they leave more often than not they clean up and leave their rubbish in a couple of bags for the council to pick up.
to me that's a lifestyle, travellers on the other hand are just tax dodgers that laugh at the rest of us calling us Gorgers (meaning we just eat up the laws and taxes that the government give out)
I guess there's a few good ones but I've yet to see any in this area
I would think your hives will be okay though unless someone tells them they have a good value.
