Nice frame.
I guess you don't need a gusset at the stearing head eh?
The brace you added should help stiffen it up and your not realy going to load it down by running on rough surfaces.
That statement is not a critique, but more of a question as to where the stresses are in a drag bike as compared to hill bike or enduro racer.
As for the rain, your lawn is lookig kind of dry.
Its been raining here in Nothern Ontario for what seems like a week.
I can here the faint sound of tribal drums out in the back yard and I will be forced to wear a pair of gum boots to deal with the puddles, dog shit and what ever else is lurking unseen in the vegitation.
Better than snow though.......
