About 25 miles. About 30 years ago, I had a stint with meth, short-lived, thankfully. I walked from the north end of my city to a suburb south of the city to my sisters house to detox after a bender and running out of money. Funny thing, in retrospect, I had just enough money left for bus fare but when I got on the bus, I was still so sketched out (paranoid) that I couldn’t bear to be around other (sober) people. So, I got off the bus immediately and walked. Not my finest hour.
