I smoke and smoke around others, I also don't leave butts on the ground or such, i throw them in my pocket or in my bag. While I feel I have a right to smoke outside I still understand that some dont like the smell in which case I will step away but only when stated.I have no problem move 10-15ft away from someone so they can enjoy clean air. just as I always attempt to be down wind from them so it doesn't blow in their face. I don't believe that smoking should be illegal in parks as long as people dont litter. Smoking is one thing but littering is against the law.
