I’ve only been here a few years but I’ve got a love hate relationship with them. My roommate last year got snagged walking near one and it took them to the ground, busted up their knee and hands. I’ve almost been pulled off my bike by them. They’re about to completely overtake my yard we’ve lost maybe 4 feet between this year and last. But also fresh blackberry pie and jam for days is an amazing thing and almost makes it worth it
