I ride bmx i have a kink kicker. Sorry no pictures couldn't find any. I also just bought a mountain bike it is a Kona Coilair Supreme Deluxe. Its older but the guy i bought i off of only road it about 5 times.
All one of the places i was riding called Sunset Ranch was some dirt trails in the woods. When the town found out about it they shut it down. So now where i am there isn't many parks, so mostly street and a couple parks every now and then because they are far away.
We have a great dirt park called 9th street here in Austin Tx .you should check it out on YouTube. What state are you in.
