How about getting him a skateboard ramp building kit or plans so that he can build his own ramp? You could also consider gifting him some tools or materials he may need for his ramp-building projects, such as a set of saws, screws, or lumber. Another idea could be to find a book or magazine about skateboarding ramp building that he can use as a resource for future projects.
Or you can get him a star map with an important date you share.
