Losing Keys

I have my keys on a large keyring (actually about 3 rings linked together) with a leather fob made at Cub Scout Day Camp in 1991, all on a lanyard.  You'd think this would be hard to lose.  NOT. Yesterday, I went to Curves.  Had to get there by 11:30 because they close at noon on Saturdays. I was almost late because traffic was being diverted due to a terrible accident (motorcycle, van, utility pole, wires down).  Got there just in time, scanned my tag (which is on my key ring along with several other scan tags) and did my routine.  Just as I was finishing up, the power went out (due to the accident).  I completed my cool-down stretches, grabbed my purse and went to leave.  I needed to get a few groceries, so I walked to the grocery store to ask if they had power, talked to a couple of employees outside, then the power came back on.  I did some shopping, then went to the check out and discovered I didn't have my keys when I went to scan my tag for discounts.  Curves was closed.  I can't get my keys until Monday morning.  Hubby came to my rescue, and brought the spare keys.  While I was waiting in the grocery store, another woman left her keys at the check out, and had to come back in to get them.
