Can we use GPSs or electronic navigational devices?
No these types of devices are strictly not allowed to be used

Does each person have to carry all their individual gear or can one person carry another's required gear?
Sure, this is what adventure racing teamwork is all about, as long all the required gear (for everyone) is with the team it does not matter who actually has it.

Can we use our bike gloves for the rope activities?
No, the gloves must be full-finger leather gloves per the gear list

Is there a transition area (TA)?
Yes, however you will not always be returning to the TA before changing activities so be prepared to carry any and all gear you think is necessary before returning to the TA.
