Campari cocktails without vermouth?

I’ve been wanting to get into Campari cocktails, since the couple times I’ve tried it I quite enjoyed the flavour. However, many of the famous ones are in the negroni family, ie they use vermouth. Vermouth is to date the only real ‘category’ of liquor I have found I just don’t enjoy the taste of, especially sweet vermouth which is common in so many of these drinks. So I’m asking here: what are some good Campari cocktails that don’t involve vermouth in their recipes? Bonus points if they don’t go overboard with wacky and hard-to-find ingredients, but I’d be happy to hear those too.
