The Civic has completed almost two full seasons of auto cross without any major issues and has been an absolute blast to drive. I’ve been slowly making changes to it so I could see how each change feels and at this point I think it’s about perfect for my driving style.

Syncthing rocks. I use it to keep my notes and docs synced between my two laptops and it’s never let me down. Recently one of my laptops went kaput after an OS upgrade and I was forced to set everything up from scratch (including Syncthing). Thankfully it’s pretty easy to set up.
