Went to Katie's Cars and Coffee last Saturday. I live nearby-- so when I go, I usually arrive around 6 am or a little after, and have always found lots of parking spots still available. I arrived last Saturday with my X at 6:15 am, and the entire parking lot was filled. I found a spot in one of the adjacent parking areas. I saw a white 3 parked near the pub entrance --- never saw the owner, but I suspect he/she must have arrived before 5:30 am.
Some amount of time after we had parked, we noticed a few other Teslas arriving. They drpve around and around and around looking for parking, and some finally parked across the street in the Safeway parking lot. At around 8:30 to 9, cars start leaving .... and so we finally got to group our Teslas together for a pic.
I guess this event is getting more popular. In the past, several of us owners have met here and have been able to park next to/close to one another. Now it appears that to do so, you'll need to arrive well before 6 am.
