Love it! It's been said here over and over that touring is possible on ANY bike. But why is it that those guys put the girl on the cheap $45 bike while they rode their nice Dawes?

Those cheap bikes are exactly right for those purposes: short tours. Had you gone any further your tour most likely would have been plagued with more breakdowns than just a broken chain. In other words, reliability becomes an issue. Nevertheless, you did right thing for this situation. Some people would have gone out and dump $1K on a new touring bike for a 5-day bike tour and then let the bike rust in storage. BTW, awesome pics!
