Might be worth checking with your local or county transportation agency. They may have a bike rack installation program or request form.
"Fred" is of course the rider "we" look down on for wearing jeans and sneaker and riding a Walmart $79 special on his way to/from his 1st/2nd/3rd minimum wage job.
Was interested when you wrote that--my understanding has been that a Fred is someone without a lot of serious bike skills who nonetheless goes out and spends thousands of dollars on a bike--the weekend Madone rider.
Then I looked on Wikipedia and found that both usages are correct, plus a third usage...

Basically, "Fred" is anyone who you look down on!
