Is there any sort of metaphysical store? Like with crystals, incense, essential oils, those sorts of things? Also, are there generally a lot of vendors open on tuesdays and wednesdays? Or only on weekends?

Yes, there is a botanica type of vendor in there. They days, im not too sure about. I only ever go on the weekend.

Yes you will find there you are looking for.

There are several places that sell incense...one of the shops sells a lot of other neat items along with incense. I went online to look at Red Barn Flea Market Hours - Closed on Monday's...Tuesday-Wednesday 10:00am to 4:00pm and Friday-Sunday 8:00am to 4:00pm...Most if not all the shops are open on the weekend...only some of them are open during the week but a great place to visit any day if the week. A must see place.

They open I think starting Wednesday to Sunday.! Yes to your other questions.

Yeah but you need to come in early in order to find what your looking for

Mostly Saturday, Sunday, Monday, and Tuesday. There's crystal stores and places to buy incense, oils, and sage.
