I plan on doing at the beginning of August. Seems that it is not technically difficult but has extreme exposure which can really freak you out if you are not comfortable with that sort of thing.
Think of going over a 500 foot deep gorge on a highway bridge, you would shoot right over it at 70 MPH.
Take the same bridge and make it 1 lane wide with no guardrails, technically its the same thing, but I'm sure your not going to go 70 MPH.
