Mussel fee/decal

Hi all,

Apparently there is a new way for CA to make some money off boaters:

I didn't really mind at first until I realized Nevada also requires a similar fee/decal for both resident and non-resident boaters. The fees are minimal but the irratating part is having to slap more decals on the boat:

I'll get over the decals eventually... Has anyone in Nevada, specifically Lake Mead or Mohave run into issues not having this decal? I spent a lot of time on Mohave in 2013 and never had a problem. I didn't even know that Nevada required this all of last year.
