The Dow University of Health Sciences is currently plying extremely ragged, run down buses for its students. Upon repeated requests, the University finally bought about 20 new buses in December last year. But these buses are standing idle since then and are not being operated. On inquiry, the university administration comes up with various lame excuses. The students and the University staff are made to suffer frayed old buses while the new ones are being 'vintaged' in rain and sunshine. -SAJIDULLAH MAHMOOD, Karachi, via e-mail, March 31.
