Not much about her last was ever revealed, so it makes one speculate. As such, I stumbled upon these images that imagine Ramona (at least in her portrayal by Mary Elizabeth Winstead) in interesting positions.

A server at McDonald's, a gardener, (possibly) a model or coffee shop worker, a football team cheerleader, or a minor league baseball player. Obviously, none of these were ever confirmed, but it's always fun to imagine.
