Hi Liz, welcome to Steemit!
I think the community will be happy to read anything you write about the interests you listed. Also, posts about your travels will be interesting, especially if you sprinkle them liberally with pics, so those of us less able to travel can still see what a place is like.
I had to look at the full size version of your last picture to see what it was. It appears to be some cool kind of climbing wall or maybe just a practice set up. Maybe you can elaborate on what that is. My experience with climbing walls is limited but I enjoyed doing it!
Wishing you all the best, and happy travels!
Thank you for the warm welcome :) yes, the last picture is a hang board, used for pull-ups, ab workouts, or finger strength training (I was just doing pull-ups at the end of a climbing workout in the picture). The wall behind it is a small section of a bouldering cave with an area for campusing (climbing with no feet, thus improving upper body strength and making you look like a general badass).
