That's a great interest to have, and there are a few different ways you could incorporate it into a birthday gift for your grandpa! Here are some ideas to get you started:
1. Tickets to a roller derby match: This would be a great experience for your grandpa to enjoy with friends or family. Check out the schedule for local roller derby teams and see if there are any matches coming up around his birthday.
2. Roller derby gear: If your grandpa is a roller derby fan, he might appreciate some of the gear that the athletes use. Look for things like elbow pads, knee pads, and a helmet to help him stay safe when he's skating or participating in other activities.
3. Roller derby memorabilia or merch: There are a ton of roller derby teams and leagues out there, which means there are plenty of shirts, hats, and other merchandise items available. Look for ones featuring your grandpa's favorite team or player to personalize the gift.
4. Roller skates: Finally, if your grandpa doesn't already have his own pair, some roller skates might be a fun and usable gift that honors his love of roller derby. Look for a sturdy, well-made set that will hold up well over time.
