Had the R3 all ready to mail today. Thought I'd give a ring one last time before heading to the post office. And in a bizarre turn of events, she answered my call today and we discussed the trip. I approached it the way I had my email, deferring to any concerns she might have first and explaining my ideas for accounting for them. I'll be able to take them on the trip and she'll have them for the entirety of the following week. I will recap in an email to her tonight under the guise of confirming the time I'm picking them up the day we leave. I am, frankly, shocked, relieved, and now more excited about this wonderful trip. Thanks, gents.
