Happy hacker safe and hacks alone

Experienced happy hacker all rounder. Happy to hack alone and in company, not silly but not a plod. Forward going . I am an experienced light weight rider but not ridden in a while. I loved trek in the past and small show but hacking out is my thing and just being around horses! Have a budget between 2.000 to 5.000. would need transportation. Have my own land and will have a companion pony for him. Will have 2 large stables. Can be out 24/7 in summer but in at night in winter. I would consider a warm blood / sports horse . Main thing is he's good on his own and with traffic etc. He would certainly have a loving pampered home hopefully for the rest of his life. Karol
