I’d love to see a photo of you zip lining! As we say in the south, I double dog dare you! Which means you must do it!
On the A/C front, I am so glad it was just a filter. My dfil and dsil who live together were having A/C troubles. It was just not cooling. Like yours, it’s up in age. They had someone clean the unit and it has begun cooling once again. They may have changed the filter too. I know the cleaning was long overdue and it helped tremendously.
This afternoon we have gotten quite a downpour. Dd and I were in Hobby Lobby when it started. We were not supposed to have rain at all so I never too the umbrella in the store. I made a mad dash to the car to pick up dd at the door. On the way home it was raining so hard and the wind blowing so hard that the rain was going sideways. Fortunately I was creeping along on a street that does not get much traffic. We were only about 1/2 mile from home so we went on toward the house. At least we had a garage to pull into and stay dry. At least the rain is cooling things off a little.
