For us it is everything.
Being retired and having zero hope of additional income, and being travelers that specialize in free parking, fuel cost is a major consideration. We stored up want money we could when nothing was open so there was no place to go, but we are about to go off to more rallies that are not free to participate and fortunately there is not much year left.
We will survive, but between this and the abrogation of major companies, this is not what I scrimped and saved most of my life to not enjoy.
