We were all a little frightened last month when Congress threatened to strip National Public Radio of its funding. (Thankfully, a last-minute deal averted that.) Now back from the brink, NPR is revved up to celebrate the 40th anniversary of All Things Considered, the public radio station’s flagship news program. Accordingly, they will be giving away 500 free Pleasant Pops popsicles today at 2 p.m. in front of their 635 Massachusetts Avenue NW building. With temps in the 80s today, we can think of no better way to celebrate.
