Hey Tom, no doubt about it, go for a ride! How many warm days will Mother Nature share with you this time of year. If you don't, it would be bad for your's and Bonnies soul, plus the gods may be pissed if you don't appreciate this gift and make it a hellish spring! All this adds up to you having no other option.
On a serious note, I went for a ride this week after the mini snow storm we had was long gone. Some residual salt, but the roads were mainly clear with just white staining outside the wheel tracks. If it is dry and you take well traveled roads you will most likely have little or none to worry about. Give a wipe of Pledge or cleaner of your choice on everything you can reach and then hose off when you get home, dry and treat again on surfaces. Many folks here live near coastal areas with constant exposure to the sea air, a little exta care in your case should keep her from being a rust bucket.
Enjoy the ride.
