A plan to manage and restore Yosemite Valle and the Merced River that runs through it encountered some rough political water Tuesday as a Congressional committee scrutinized changes that would alter some of the parks most popular recreation activities. The scrutiny by the Public Lands and Environmental Regulation Subcommittee of the Natural Resources Committee was initiated by California Congressman Tom McClintock. The plan is now being worked over by park officials after months of public hearings. The final plan is due to be finished by the end of the year. Vic Bedoian reports from Fresno.
