When do they sell the tickets for MNSSHP?

[SamRoc]

We went this past Oct 7 to MNSSHP and we got our tickets about 2 weeks in advance, figured they were so easy to get as it was early in the month. Was wondering what time of year do they go onsale usually. Want to go for Halloween next year and I heard it sells out. Was thinking probably about August but wasnt sure. thanks.

They went on sale the end of April this year.
