Where do you have trouble with hundreds? I could imagine somewhere like Kansas but in any normal city that shouldn't be a problem. To be fair my niece thought it was odd that I had a few hundred in my wallet but at my age I prefer to have plenty of cash.
Oddly now that I live in Germany instead of the US, cash is more common since systems are down more often and it's not considered all that weird.

I wasn't aware of payment systems being down often in Germany, but in any case that would only be a minor contributing factor. Germany's dependence on cash is mostly due to deeper cultural reasons.
