Oh, and one other thing: Chuck told my friend and I that ALL FOUR
OF US were thrown from the boat.

If that was the case, then you must know how long my friend were
in danger - because the first time that I again saw Chuck - he was
in the boat, holding the T-Grip out to me......

How did HE get back in the boat???

Experienced rafters, a group in which most guides are included,
can climb back into a raft by grabbing onto the side handles or
rope-line, kicking the feet for acceleration, and doing a pull-up.
When a raft flips upside-down, the situation is similar but worse.

Before I answer all your questions, if someone else doesn't
answer them to your satisfaction, let me ask you for more details.

During the ABC Company's safety talk, did they mention what to do
if you fell out of the raft? Did they give you pointers in how to
stay in the raft by putting weight on your feet, as if you're skiing,
or holding onto some handle?
