I had a Wrangle for a long time, but it had the full metal doors on it and wasn't that easy to remove and re -install. I did ride with the top down. On the other hand I have rode my motorcycle and my Vanderhall nude. Well the bike ride was mostly nude, still wore my helmet, boots and gloves. I drove my VV out on country roads. There is no hiding in it either, one because it sits so low and open, secondly because it draws attention. Got to admit it feels great with the sun and air rushing by.
Now I feel really lame. I just confessed to a buddy from here the other day that I hadn't even taken the back and / or doors off of my Jeep yet (and we've had it 2+ years), let alone drive naked with it like that! There are some mountain roads here that you *might* be able to get away with it during the day. It could easily be done at night, but temps often drop 20+ degrees, so it could be a bit chilly. This is definitely food for thought and now I have to make it happen :)
Id be worried about burning my leg on the pipes! Perhaps horseback riding would be better?
Was Equus your example.
Daniel Radcliffe had the lead in a London production of Equus when he was 17, but he couldn't perform the role in NY until he turned 18 due to child pornography laws.
