Yes, I find I get bored working on the resistance machines. I think it might be because you have to sit down to use them, so in between sets you're sitting instead of standing.

My gym is a ten minute walk from my house, which is fantastic. I love doing handstands! I used to walk around on my hands randomly just for a change in perspective. :D

Thank you for mentioning TNRoLfW. I think the shorter workout you mentioned could be really useful for adventure race training, if alternated with my usual workout.
