Welcome to irv2... and welcome to the Lord's family, also.
In California, at least several years ago, many of the state campgrounds had services conducted by local churches coming to the campground. It has been a few years since we camped regularly at state campgrounds, so I don't know how widely spread this practice may still be in our state.
Knowing we are going to be in a community over the weekend, we usually scout out some of the local churches and pick one to attend on Sunday. Some of our most meaningful worship services have been in those churches.
Best wishes, and God bless you as you seek to worship Him, even on vacation.
