Back in April, Constants announced they were selling their 1995 International School Bus that had been modified to run on Veggie Oil. They needed something smaller since the heavy star-gazing band downsized to a three-piece and didn't see the use in having such a large touring vehicle. But they haven't sold the environmentally conscious bus yet, and not because there haven't been any offers. The band just can't part with the baby they built.

"We got a couple offers on it," guitarist/vocalist Will Benoit told Noisecreep. "When you go to sell something that you put so much time and work, and spent so much time in, you don't realize how much you love it until you try and sell it on eBay and realize no one else loves it quite like you do." He confessed that the offers they have received yielded no one that they believed would give the bus the same attention and care they have.

The bus -- that Benoit estimates is on version four of their upgraded and modified system that can switch between diesel and veggie -- came when the band decided they wanted to tour longer than just little two-week jaunts. "We realized the only way we could do that was to get a bigger vehicle that we could sleep in and have days off in comfortably," he said.

All the members of Constants are very involved in making as much of their lives, and the band's, as environmentally aware as possible. Currently, Benoit is building a studio that the band will use to record their next record and solar panels will be helping power the space.

He said, "We're big into green touring and so far, the best way we can show people that is with our bus. It's defiantly an eye catcher," Benoit laughs, presumably because the metal blue bus displays a bright white painted phrase reading 'This bus runs on vegetable oil.'

"We've met a lot of bands on the road and kind of helped through the process of converting their vehicles and showing them that you can be a touring band and be doing something for the environment that's positive," Benoit said.

Only a few years ago, bands bands who went out of their way to burn less fossil fuels were few and far between, but the number is growing, and Benoit sees it. "When we first started doing it, it was just, 'Talk to the guys in Piebald, because they're the only band doing it,'" Benoit pauses, correcting himself. "Obviously there were other bands doing it, but [Aaron Stuart] from Piebald ended up helping us out quite a bit. But now there's tons of bands. We go to grease traps behind restaurants, and you see the remnants of a band that's been there -- rubber gloves hanging out back there. They're always telltale signs that a band has been there in the last couple of weeks."

On top of the environmental achievement of having the bus, which you can see pictures of, they've saved money on the road by having it. "We did from Boston to Florida to New Orleans to back up the coast and I think we spent about $150 bucks."
