This year was my first time at trax since like 2008. I love how reasonable of a drive it is from the south hills area of Pittsburgh- it only took me about 20 minutes to get there .
Trax has a huge farmers market, which is awesome. The food isn't overpriced, but the decorations that they sell are a little on the expensive side. They have a pretty decent sized area full of wine which is clearly my favorite spot in the shop :).
My boyfriend and I came here on a Sunday around 1- during a steelers game... And it was still PACKED. I mean, packed. The line for the hayride was insane, so we didn't wait for it. The lines to buy pumpkins were insane as well, but we were able to sneak inside where the lines were a little smaller. They have an awesome selection of pumpkins! And they weren't too pricey either.
They also had a ton of flowers and lots were on sale due to the fall season. I ended up finding gorgeous orange mums for my mum (hehe) for only $10. Not bad!
Trax is awesome, but I would recommend coming on a weekday if possible, to avoid the insane crowds, ESPECIALLY if you're coming in October.
