This is something I did for the hiking club I belong to, and I'm going to suggest it because it's really great!
What's more, it helped me figure out how to split it up and create a 6.5 km route, which I can also suggest to the other walking group.
That way, our club can go out together and meet up for a picnic at lunchtime. There's a great spot near the ponds. 🥰🐸
So I'm absolutely delighted!! Thank you so much!!! ✨️🤗🥰.
