Altitude

(1929 August, in Buffalo, Wyoming)
[Polly and three friends drove out to Yellowstone Park; on her way back she wrote to Lorin.]  Have you ever been affected with the altitude?  We drove over the Big Horn Moutains today, and they were worse than the Rockies.  Tommy [Tucker] and I are the only ones bothered, it seems.  The pressure was annoying, but when all the tubes began to pain, we nearly saw doctors.  Usually coming down, our hearing comes back with a rush, but today things seemed farther away and stayed gone longer.  Most odd.  But we feel better now, all but a little dizziness,ich is going fast.
