Just put a 10 ft chicken wire fence around your garden, fill a paddling pool with water and leave a small pig with the dogs breaking it`s hind legs... Let the dogs be dogs man and go on holiday
It's a nice wee spot, but doesn't feel like being abroad, all Brisith shops, British street signs etc. The town right across the border on the Spanish side is a hole. Na it's nice, you would love it.
And what is your point, it's a nice quiet wee area to get some sun, cheap booze and fegs and watch some football for a few days.
No point really, other than I maybe get bored by familiar surroundings and personally prefer somewhere I'm not familiar with as a holiday. There is a chance I'll end up living in Gibraltar at some point though, given the amount of offshore companies based there - but it wouldn't be my first pick of places to live all other things being equal. Property is too expensive and small, you see the same people everywhere and as you say La Linea is a ****ehole.
I won't really be holidaying there just a getaway for a few days whenever they get a decent team to play.
It has the added bonus that you can wave the Union Jack at the folk across the border, thus winding them up no end.
