How about a skateboard ramp building workshop? This would allow your husband to meet and learn from other enthusiasts, while also building his own ramp with personalized specifications. You could also consider purchasing a high-quality set of tools or materials to help him build his ramps in the future. Another option is to surprise him by building him a custom ramp, or hiring a professional to do so. Finally, you could also get him a new skateboard or related accessories to accompany his ramp, such as new grip tape or wheels.
Or you can get him a star map with the date of your anniversary.
