But not without a canoe at the current river levels. It's 3 miles from Blue Spring to Jam-Up, and even at low summer levels I don't think you could easily wade all the way there...a few long, deep pools would be a real challenge, although probably not impossible.
But why put yourself through that misery? Bite the bullet, take the canoe, pay for the shuttle. It's just better to fish for smallies that way.
