I'm always on the lookout for museums and family attractions that offer a free admission day once in a while.

But this is the first time I've heard of any place offering free months.

The Owls Head Transportation Museum, a great collection of antique cars and airplanes near Rockland, is doing just that. Admission will be free for everyone in January, February and March.

Normally, admission to the museum is $10 per adult, and $25 for two adults with their kids.

For a complete rundown of what the museum offers, including directions, check out the museum's Web site.

Or call the museum at 594-4418.

If you haven't taken a free horse-drawn wagon ride around downtown Portland this holiday season, you better hurry.

This weekend is your last chance.

The free wagon rides, organized by Portland's Downtown District, are a great way to see the colorful holiday lights in the Arts District and in the Old Port.

The rides have been running on weekends since Thanksgiving, and the last three days for rides are this Friday, Saturday and Sunday.

The wagons leave from Monument Square, on Congress Street, every half hour. The wagon ride hours are: 4 to 8 p.m. Friday; 2 to 6 p.m. Saturday; and 1 to 5 p.m. Sunday.

For more information, go online at the downtown district's Web site. or call 772-6828.

You can also catch a free horse-drawn carriage ride in front of L.L. Bean's flagship store in Freeport every Saturday and Sunday through Dec. 28 from 1 to 7 p.m.

If you're thinking of a family outing this weekend to cut down a Christmas tree, you might consider adding a sleigh ride for $5.

At Lank Tree Farm, 1 Sawmill Road in Kennebunk, there will be rides in sleighs or wagons pulled by a team of Belgian horses, Molly and Beauty. The rides are from noon to 3 p.m. Saturday and Sunday.

It's $5 per person, but free for kids ages 5 and under. So if it's just you and a couple of your little ones, it's a pretty cheap ride.

The farm has cut-your-own trees, plus wreaths, garland and centerpieces. For more information call 985-4925.

If you missed Portland's big tree lighting and family festivities last Friday, just head over the Casco Bay Bridge this Friday for South Portland's yearly free holiday shindig at Mill Creek Park and city hall.

South Portland's Holiday Fest will begin Friday at around 4:30 p.m. with horse-drawn wagon rides. From 5 p.m. to 6:30 p.m. kids can have pictures with santa at the city hall. There will also be student groups singing.

But the highlight will be at 6 p.m. when the switch is flicked to light the dozens of decorated trees in Mill Creek Park. You can find the park by going over the bridge and staying on Broadway until the intersection with Ocean Street. The park is on your left.

For more info, call the city offices at 767-3201, or go to the town's Web site.
