I beleave ya can have up to 5 without the extra permit while ice fishing atleast thats the rules i been going by whats your take on it http://fishandgame.idaho.gov/cms/fish/rules/definitions.pdf
..I've always thought it was 5... But in my opinion 2-3 poles is more than enough.. Me & a buddy have fished palisades with 5 apiece & it was just too much of a hassle to keep the holes cleaned out & the eyelets thawed out
