Getting a Nitro Stampede for Christmas... I have numerous BIG fields near my house... However some of the the grass/weeds get pretty high... How high is too high for the grass? Same height as the tires? Twice the height of the tires? Half the height of the tires? ??? I don't want to go to all the trouble of carrying the truck out to a field and find out I have to go to a different field because the grass is too high... (Yeah, I know NO GRASS is the best, but I don't have any fields like that)... Thanks.
