QUICK HITS.

Call to camp: Backpackers who want to camp this summer in the Enchantment Lakes area near Leavenworth in the Washington Cascades must get a permit, available for $5 by calling [phone]. The Enchantment area is part of the Alpine Lakes Wilderness, 400,000 acres of peaks and lakes between Snoqualmie and Stevens passes. The number of hikers who camp overnight in the area is limited to protect the fragile high country.

For car-based and RV campers, reservations at some of the most popular Washington and Oregon state parks also can be made with Reservations Northwest, [phone]. For reservations in some of British Columbia's provincial-park campgrounds, phone Discover Camping at [phone].

Expansion go-ahead: The California Public Utilities Commission has approved plans to expand the Napa Valley Wine Train. The expansion, planned over the next two years, will include the addition of a second train and a passenger station in St. Helena and other locations, where riders can get on and off and will also offer shuttle bus services to nearby wineries.

The Napa Valley Wine Train travels 36 miles past 26 wineries through the heart of California's wine country. Passengers dine aboard authentically refurbished 1915-era Pullman cars pulled by 1950s-vintage Streamliner locomotives. Reservations: [phone].

Road closures: Some Northwest roads - and even the Oregon Museum of Science and Industry in Portland - remain closed after this winter's heavy rains and floods. The riverfront OMSI, a hands-on, interactive science museum, has been closed since February because of damage from Willamette River flooding, but is scheduled to reopen May 24. Information: [phone].

Washington state roads closed because of flood damage include Highway 123 over Cayuse Pass on the east side of Mount Rainier National Park (call the park at [phone] for information) and the Hoh road on the west side of the Olympic Peninsula, which leads to the Hoh Visitor Center and rain-forest trails in Olympic National Park (call [phone] for information). The Hoh road is due to reopen later this month.

Camp for free: The Mark Twain National Forest, scattered throughout 29 counties in southern and central Missouri, will open its 650 campgrounds June 7-9 for camping free of charge. The event is being held in conjunction with National Fishing Week, when the Missouri Department of Conservation also offers free fishing with no license required.

Park it here: Parking is now free at Logan Airport in Boston - for the first hour. After that, short-term parking soars to $10 for the second hour, before falling to $3 for each additional hour. The free hour was recently approved by airport authorities in response to complaints that stepped-up federal security enforcement was preventing curbside stops at the airport, forcing drivers to pay $5 to park when briefly dropping off or picking up passengers.

Downright tacky: ``The Tackiest Souvenirs in the World,'' a collection of more than 200 of the very worst in tourist thing-a-ma-bobs, will be on display June 27-Sept. 9 in Toronto at the Queen's Quay Terminal at Toronto's Harbourfront Centre. Information: [phone].

Up in the trees: Ten originally designed tree houses - including one that is a giant butterfly and another filled with grass-covered furniture - will be displayed June 1-Sept. 2 in the 66-acre Dallas Arboretum and Botanical Garden. The Arboretum is at 8525 Garland Road on White Rock Lake; open 10 a.m. to 6 p.m. daily; admission $6 adults, $5 seniors, $3 children ages 6-12. Information: [phone].

See-through ships: The Carnival Destiny cruise liner, set to debut Nov. 24, will offer scenic balconies with more than half its 740 ocean-view staterooms - and the balconies will be made of clear glass rather than metal to provide unobstructed views. The ship will sail year-round from Miami on alternating seven-day eastern and western Caribbean itineraries.

Scoundrels, beware: Maryland's official state sport is jousting.
