I've been doing variations on this for decades. I'm fortunate enough to live in a rural area in the US with open space within walking distance, but I've done it in urban areas too. Some ideas: - Walk every road and alley in a small town. - Bicycle every unpaved road in an entire county. - Follow every trail in a park. - In an unfamiliar city, try to walk to destinations with minimal map or GPS use. This can occasionally lead to feeling unsafe, so use care. Before ubiquitous GPS, I used to carry a compass everywhere to help with this. - Pick a direction and walk for a fixed amount of time, then come back a different way. I once walked 50 blocks in NYC this way during a business trip. A friend of mine has spent many years hiking to the top of every publicly accessible peak visible from a hill near his house and has had some wild adventures as a result.
