3 sisters + 1

The 3 sisters (Vy, Ky & Py) are being joined by friends at points along the adventure. Here's an excerpt from Ky's friend, My:

Okay Ladies,
I booked my flight so I am going to swoop in on the “sister vaca”; hope that’s going to be okay…..but if not….well, you’re stuck with me anyway! I get into Vegas on Monday and I leave PHX on Sun (you may want me to just return the SUV for you). I will be happy to chip in on all expenses, although I’ll probably have to budget differently as it will cost me more than $15. a day for drinks!!!! Ha! Don’t think I can cut back on that breakfast allowance……hmmm….maybe I’ll just skip dinner---course with me along to share expenses, everyone can up their booze budget. I’ll check with my dad this weekend and see if I can get him to pull some strings on the NR deal. I’m working on the rental car to "SG" now. If I can’t get a one way rental, Ky, you might have to pick me up in Vegas. I think I can work it out though.
Happy trails!

She refers to the budget which Py worked up. That's what happens when you get a chemist, a biologist and a mathematician on the road together. Now we will be joined by a librarian, My.
