Great track Just 3 little suggestions to make it better.
1. Fix the Spawn (Have not tried racing because i read it doesnt work right) but you should move the spawn from the inside of the barriers to the open pit like area.
2. Lower the track just a little bit (closer to the base terrain) so when you spawn or use Backspace/I to respawn you dont have to mousedrag the truck up from from half way under the terrain.
3. Fix Racing (read track is sideways)
Besides those its a good track so far
