This Friday, the main Montana routes into Yellowstone National Park will be open to automobile traffic. A lot of folks will probably wait a day to get in though, because Saturday is the first day of National Park Week. During National Park Week (April 21- 29), park entrance fees will be waived. Park Spokesman Dan Hottle expects that the park will get pretty busy this weekend, but says that it won't be nearly as busy as thing get during the summer.

The rest of the routes into the park are set to open next month.
