I've read some other posts and it seems this is a big no-no at present, but my outdoor venue is literally rock and gravel that I'll be going up and down in addition to where we will be standing will also be gravel/rock/dirt. I am a little concerned about the dirt/dust that my train will get.
What would you do or not do and why? Thanks everyone!!!
Edit: a different venue is not possible. And guests will be aware this is an outdoor venue at a nature center.
