I've never hiked with pepper spray before but decided to start this year. I'm flying to my trailhead. I know I can't carry pepper spray on the plane but I could not get definitive information from Delta Airlines about whether I could pack pepper spray in my checked backpack. The TSA regulations don't say it is prohibited. The person I spoke to on the phone said I'd probably be okay, but it might be confiscated. Not much of an answer. Does anyone have experience? Thanks.
