I think that basically answers my question.
My hope had been to get the HaD early enough to put it all together and take Light Rail up to Folsom to cover the first half of the ride. Without using public transport, it's a two day trip each direction. Since the bike will still need to be put together when it gets here, there's not much of a chance of that happening. Luckily, there's enough summer left to play with the HaD later.
We haven't been able to make as many bike trips as I had hoped this summer so this next one is especially vital for my sanity. It'll be hilly and hot but luckily, we'll only be 40ish miles away from help at any time. Besides, life is always a crazy adventure with these two monsters!
