Five Star Gift Ideas

That's great! Here are a few gift ideas for your grandpa who loves urban exploration:

1. Membership to the National Trust for Historic Preservation: This organization works to preserve historic buildings, homes, and neighborhoods across the country. Your grandpa can use his membership to access discounts on admission to historic sites, and attend exclusive tours and events.

2. A book on urban adventures: There are many books that offer guides to urban exploration and hidden gems in cities across the world. Consider getting him a book like "Exploring Abandoned Places: A Guide to Urbex" by Michael Fattorosi, which offers tips and techniques for exploring abandoned places.

3. A drone: Drones can be used to explore the urban landscape from new and unique angles. Your grandpa can capture breathtaking images and videos of historic buildings, hidden alleys, and other urban features that he is passionate about.

4. GoPro camera: A GoPro camera is small and versatile, perfect for capturing shots and footage during urban explorations. Your grandpa can wear it on his body or attach it to his bike or backpack, making it easy to document his adventures.

5. Personalized map: Consider creating a personalized map of the city where he likes to explore. You can highlight his favorite spots and include notes and memories that he shares with you.

Or you can get him a star map with an important date you share.
