if you don't have get one.... My truck broke down at 3:30 am this morning 50km into kootenay park outside radium. I thought what to do, i didn't want to start walking and leave all my gear. then realize my spot has been in the truck since november... maybe the batteries are dead maybe not...so i send a message to my gf but then start thinking she never checks her phone at the best of times so she is not checking at 4am...so i send one to my brother he's way better with the phone but its really early still... so I send one to a buddy who's always up really early and tell him to call my gf and brother....sure enough my brother came to the the rescue.... i was never in really danger could have started hitch hiking or waited for a parks truck.... but it was nice and reassuring to send out a spot and get an answer...truck made it home tonighti think its the wheel bearing should have it fixed tomorrow
