hey chief - tiki lounge is great but can get a little collegiate on the weekends. if you can get there earlier in the day/evening you'll be golden. Visit the Strip District on a Fri/Sat/Sun morning for some wild street market shopping/eating/drinking.

regarding haunted harbor, I was keen on going but I saw they were sold out so I wrote it off. If you don't have any takers by Saturday, DM me I may be interested in a ticket.

Lastly, there is an free event/outdoor Vintage clothing market going on Sunday morning 10/30 from 10-4PM at the Highline, a repurposed commercial complex near downtown. They have a rockin' surf band playing around noon [The Yeggs]. Stop on out and say hi to the guitarist ;) - Wish I could link you some details, just search 'Pittsburgh Pickers' on IG or FB you should be able to find a flyer.

Good luck mate, just hang around maggies farm, HH, tiki lounge, and you'll link up with some cool like minded folks.
