It might not be the best idea but I would. Lol. I would just make sure I didn't flat out lay out in the sun. I just got cursed out (not really) but a colleague of mines who has lupus also. She noticed my skin was darker & she claims my face was swollen last week. I bought a convertible in March so lately I've been able to ride around w/the top down. I try to only ride around in it before the sun is fully out in the morning and @ night. As long as the repurcussions are only some swelling and slight pain in my joints, I'm riding in my damn convertible!!! Lol.
