Thank you! I really appreciate the kind words! I do have a concrete crossing and 2 different kinds of crossing guards that are included in my pack, I do realize that the concrete is sometimes higher than the road it is crossing. On dirt roads I just adjust the road to slope up to it, as you would in real life. However on roads I see this could be a problem.. I will take a look at it and see what I can do about reworking my crossing!
