just started this a few days ago, all the ramps are tested and working fine. Still not done with all the props and add-ons might be some glitchiness but i wanted to share what i had so far.
I straight up stole the miniramp in the center from Iamsnail's Backyard BBQ park, i just took off the coping. Its really a great ramp, its two ramps overlapping.

theres another ramp hiding behind the big OATS Bank, but this gives you a general idea.
