I'd like to share some more of my track layouts and ideas. I found that I really enjoy testing various track parts and Hot Wheels sets, for example I used the 4 Lane Start gate box, connected to basic track, then into a split track segment, and then into the Curve kicker track set. Eventually I want to custom build some wide track, likely made of cardboard, but I would need it to switch back into a single lane of track towards the end of the track somehow. I also plan to use Lego Road base plates to make the wide track segments look soemwhat more like a real road, but I have also thought about getting even more realistic types of road tape to use that on a custom track someday. I have the 4 Lane elimination track on it's way from Amazon. I can't wait to try that out and find cool ways to use it and maybe connect it to other tracks and track compatible sets. I also picked up the curve track set which should arrive in a couple days.

I really like the Hot Wheels Curve Kicker, combined with Blaze Blast, they work really well together.
