been on missinapi river twice some years ago.
i didn't plan trip as it was another guy's choice of spot's.
remember outfitter dropped us off and we caught the wilderness train back out.
can't remeber details off hand but WHAT i do remember that both times we went was in spring and the black flies cut the trip short both times!!
not my choice but the guy's who planned it!!
even with 100% deet, they couldn't deal with the bugs.
on the lake's it was better but the river sections were bad!!
not to discourage just something to consider??
would look into bug shirt or similar item just in case??
