We had a lot of rain today but I was able to get the inside walls completed.

Here is a look at the Oval layout. Note: there is a way for a car to get back on the track if it does go over the inside wall.

Here is a look at the larger track layout. Adding the inside wall section adds a 90 degree left turn and 28' more track at the center line.
Note that a car that gets over the inside wall has a way to get back on the track.

Here is a closer look at how a car that goes over the inside wall is able to return to the track without any issue.

The yellow wall (picture right) is just laying there at the moment. I will be attaching it to the fence line soon if I do use it.

The PVC holes will be plugged before the racing starts.

The concrete pad is almost 30 years old and has a few cracks. The cracks do not effect the cars. But, they do help dry the track quicker after it rains. So that is a plus for sure.

I was able to get the inside walls done but I was not able to run any laps today because of the rain.
Below is a short video on how I bent and or formed the 1" thin wall PVC pipe used for the inside walls of the track pictured above.
I should have a hot laps video up in a day or two.
