20 feet is a long distance, about one and a half car lengths.  I’d say that 80% of cars in Cambridge parked next to an intersection are within 20 feet of it.  This gives the meter maids a lot of leeway in deciding who to ticket.  So on a weeknight in Harvard Square they can evidently go down the street and ticket all the cars that are near intersections.  Beware!

Yesterday’s Wall Street Journal has an article on people who make lifestyle cutbacks in order to increase their charitable giving.  Interestingly, religious faith is not mentioned.  I wonder if the article intentionally omitted it, or whether the people sampled were non-religious.  And I wonder in general whether religious people (including Christians) give a higher percentage of their wealth to charity, excluding their own place of worship.
