lol so u wanna knwo how to do them or not to run in a car or house when ur doing them??? it seems like u can do them but you have not to much control on he where you are going. If that is the case...

you knwo how you fall to one side or the other before stabilising the bike again...well when this happens, notice that you will be going to one side or the other. you have to do this purposely(not too much). you have to move your weight a bit to the side you want to go and then stabilize your bike by switching your weight back. Doing this will make you turn to one side or the other. It pretty kewl when you can actually do it. And not run into cars...

which brings me to one of my story. Doing a funny trick...
I rode from school to my house sitting on my handle-bar and pedalling backwards...do u get the picture. I turned into a side street and wasnt looking behind me because tehir was a big truck passing me by. So my front tire hit the thing a car was pulling behind it....the car was parked and i went over my handle-bar which i was sitting on and fell right in. I wondered what i fell into and what had happened for a few seconds before realizing waht had happened. Really funny....so I went back on my bike and rode home as fast as i could....the guy was staring at me in the window...

sorry for the spelling mistakes
thx.
