Actually, you're way off base on that one. The first thing every domestic pro learns is that EPO and test are neither expensive nor are they hard to get. There are plenty of guys who will bring it up from Mexico and are more than willing to sell it to you. And let's face it, Horner new pretty much all there was to know about doping by the time he landed back at Webcor. It's long been noted how a bunch of amateur Cat 1's suddenly started riding a lot better once Horner got there. So, this tale that Horner was taking cough medicine while the others where on full programs is just that: a tale. Also, remember that while the budgets may be smaller, testing in domestic races almost non-existent, both OOC and IC, but particularly IC. Most races don't have the money to test, and the riders know it.
Not saying he's not a talented guy, or that with a "level playing field" he wouldn't be one of the best. And he seems to be a pretty good guy. But let's not let that get in the way of reason here, or pretend that hard-core doping doesn't go on with guys on small teams. It does.
