Scuba?

I've got a ride planned for tonight... too bad if it rains. I can't control
the weather, so why should I let it ruin my evening..
I was trying to think of an outside activity where the rain wouldn't effect me...if I really was in to Scuba diving....hmmm Sun would still be nicer though, it tends to get a bit dark down there. I haven’t
been scuba diving in years and not sure if I could do this activity
without dying anymore and that is a requirement I have. The bike has
fenders and a light so how bad could it be…a few hours tops, piece of cake and I don't have to worry about any sharks or running out of air.
