a few more ideas:
1)I would like to see a race track built on the water in the ocean in the pyrate bay area as its vast and unused. Then add a boat mount for sell in a shop in the area so ppl who dont have the cloud or other water treading mount can race. Also why is the Horse Race track closed off when an admin is not hosting events? I don't see the harm in being able to practice the course whenever or players hosting there own races against friends. I guess you could build a track in your gh for that.
2)Monthly weekend quest. just like it sounds a different quest every month only available for 1 weekend during that month. I figure it wouldn't be to difficult to put together a quest for ppl do once a month all though it does seem to take the admins for ever to complete projects....cough still no train cough cough
