BOSTON -- Two Colorado men made a stop in Massachusetts this week during their 12,000-mile cross-country road trip on a golf cart.

So far, Andy Raney and Jeremy Make have made stops in Phoenix, Los Cruces, N.M., Austin, Texas, Houston, New Orleans and Atlanta during their trip.

Make said they have had a lot of reaction from other drivers.

"(Drivers have said) everything from 'Get off the road' to 'What are you doing?' to 'How fast does that go?' There's a lot of yelling because it's very loud," Make said.

The golf cart is modified with a gas engine that gets 35 miles per gallon.

"It has parts from every year -- a Honda steering wheel, grate from a house to get our exhaust out, it's a hand-built car," Raney said.

The cart has a horn, windshield wipers and lights, and it's fully registered and legal.

The two are shooting a documentary about art and keeping a video blog of their encounters. They hope to be home in Colorado by the first week of September.
