Query: Comment on ``Insulator-to-Metal Crossover in the Normal State of
  $La_{2-x}Sr_xCuO_4$ Near Optimum Doping''   We underline and comment some features of the data obtained in the beautiful
experiment by G. S. Boebinger, Y. Ando, A. Passner, T. Kimura, M. Okuya, J.
Shimoyama, K. Kishio, K. Tamasaku, N. Ichikawa, and S. Uchida, Phys. Rev. Lett.
77, 5417 (1996). While in our general interpretation we agree with the authors
that ``It is possible that charge ordering could underlie the unusual
insulating behavior'' observed ``in all underdoped LSCO samples'', we further
notice that some specific features of the data are most naturally interpreted
in the light of our proposal for an incommensurate charge-density-wave
quantum-critical-point scenario.
