I practice every day more or less. Prolly hasn't been a day that's gone by in 3 years or so where I haven't had a golf club in my hands for at least 5 minutes. At least in front of a mirror or just holding it fooling around with things, etc. It's always on the mind basically. It's pretty weird....I have swung in my garage and done mirror work for upwards of an hour sometimes in the winter lol.....very weird....well-you guys prolly know how it is lol.

My computer/garage/backyard is my "lab" basically.
Practice in the backyard lots (I can hit about a 60 yard wedge back there)....my fricken yard looks like a driving range.....holes everywhere.....my dad hates it lol. But that's ok it's for the better.
...
Ya I usually get a golf dome membership for the winter....prolly will get a range membership this summer....we'll see.
Video my swing sometimes.....not all that much. I just use it as a refresher from time to time to see how things look and if there's anything standout that I've missed or something that I think I'm doing but I'm not doing or w/e.
You'd be surprised what you see sometimes lol. Never knew I was swinging with a Single Shift until I saw video.
I make most changes w/o it tho for sure.....just based on ballflight, etc.
