Cricket is basically Backpacking Barbie. She has been on enough of these trips to realize that she doesn't need to go overboard with survival supplies, but she is well prepared. The combined worth of her personal camping gear and chic camping outfit is well into quadruple digits. Notably, she brings along her own fishing gear, a trashy romance novel, and her History of Magic notes.
Before leaving, she asked Maggie to take extra good notes in class (not like she needed to remind her!) and asked her to collect anything she may have missed.
Considering most of Ebonhide is on this trip, I imagine most of them walked up Bear Trail together, but she specifically stopped at the Ebonhide Senior boys cabin to scoop up Nate.
