..explain HOW this helps the disabled?

A 10,000 mile road trip (and motorcycle) is an expensive proposition, plus the time and expenses of the motorcyclists along the way.

All of those expenses MUST add up to more than the $7,000 raised (per the article). Plus, if Tuccelli has declared himself a charity, he writes off all of his expenses from his income taxes.

Charity and foundations are good money-makers.

Bikers like riding their bikes. Each biker probably spends $1200 over the course of the 3 week ride, assuming they go the entire way. Think of the last big trip you took, 6:47. Have you been to Hawaii? How about a cruise? You probably spent that much money in just a week. These bikers are doing something they enjoy and spreading a message at the same time.

"Being deaf myself, I know how important it is for children who are deaf to be able to communicate with their families. I'm trying to spread the word that deaf children do not have to be isolated. They do not have to be frustrated. They can have a normal, happy life." Mr. Tuccelli is a deaf man who teaches sign language and makes about $64k per year. Even if he has figured out a way to write off $1200 a year to do a charity run, good for him. I can think of other less worthy write-offs he could have picked instead.

So they're spreading their message and raising a little money while doing something they enjoy. Sounds like a good cause to me.

If you go to his Alaska Bike Run website, you can read how money is raised for SKI-HI - people can either sponsor a biker at 1/10 of a cent per mile, up to any amount they wish to donate. Mike has been riding motorcycles since he was a teenager, and has been deaf since birth. This Bike Run gives him a chance to do two things he's passionate about: ride his motorcycle and raise money and awareness for deaf/blind/sensory-disabled children and their families.

How it helps the disabled is better asked of SKI HI. All the money donated goes directly to that organization. The bikers pay their own way.

Your comment, "Plus, if Tuccelli has declared himself a charity, he writes off all of his expenses from his income taxes."is very telling.

I wonder where you might have come up with that "IF"
