Aero Pines Park

If you love horse riding like me you can also try it in SL. First I bought me a horse. I can attach it to my avatar so I can ride it everywhere because no need to rez unless using the saddle for passengers.
Then I looked for places in SL that have nice trails for horse riding and I found Aero Pines Park, 9 sims of pine forest. You can use a free horsy there but can also enjoy other nice things, like ride a horse carriage,  sledge, even an air balloon. At the moment the sim is in full winter decoration, it's just awesome to wander around at the many spots to visit. Go here and explore yourself.
