Because, friends, say "American as apple pie" all you want, but if you are nearing the start of the traditional tryptophan coma, there are only two pies that are truly worthy of being served at Thanksgiving - and this has been proven by international experimentation.

I once asked a bookseller at a large indie store how many people would have to buy a book for it to get the attention of the store buyer and cause an additional order and they said: Three.
I see some book piracy discourse, and, to make a positive argument in favor of buying books, your marginal ability to influence what books get published and support the careers of writers you like is massive compared to most other forms of media.

I bought 7 gallons of gas today. I looked at the vehicles around me & ran some calculations.
We drive 1/3 the natl avg in cars that get double the US mpg. So we spend 1/6 as much on gas. That's $6,000/yr (CA gas prices).
Mandatory car ownership & arms race in vehicle size/weight is expensive!

I went to Costco by car today bc we needed gas. After filling the tank, parking was so challenging, I almost drove home to get my ebike. It's only 2 flat miles, residential or bike lane or wide sidewalk all the way

Ex-president to start serving term in 12 sq metre bedroom in police base in Brasília after time for appeals elapses
Brazil’s former president, Jair Bolsonaro, has been ordered to start serving his 27-year sentence in a 12 sq metre bedroom in a police base in the capital, Brasília, after his conviction for plotting a coup.
The far-right populist, who governed Latin America’s largest democracy from 2019 until 2022, was handed the punishment in September after the supreme court found him guilty of leading a criminal conspiracy to stop his leftwing rival, Luiz Inácio Lula da Silva, taking power. Continue reading...
