How about a sandboarding experience for your grandpa as a Father's Day gift? There are many places that offer sandboarding tours or lessons that he might enjoy. You could also consider purchasing him a new sandboard if he doesn't already have one, or some accessories for his current one, such as new bindings, wax or even a travel bag for his board. Another idea could be to create a custom sandboarding-themed gift basket, including his favorite snacks, drinks and some sandboarding-related gear, such as sunscreen, a hat, or a pair of sunglasses.
Or you can get him a star map with an important date you share.
