Google map data from 2006: 43° 32' 06" N, 80° 13' 35" W. Field aligned NNW to SSE. Stands on the west side of the field as shown on Tiger Cat home page. Major change on east side of the field moved the lamp standards eastward into tree line and added a forth set. Field still natural turf I think, (forgot to check) and the yard lines and field perimeter are permanently marked out. The 9 lane track still runs around the football field.
When I visited the site 28th of Nov there was a group of people (about 6 to 8) viewing the stands from the field. My camera wouldn't go to the X10 zoom so I have no idea who what/they were.
The stands themselves are all bleacher seating. YESSSSSS!!! (I was forced into one of those tiny 500 level seats at the GC and it took me over a day to recover, and no I wasn't drinking either). The stands run from 20 yard line to 20 yard line, and are about 28 rows high. MY estimated EXISTING seating 2800. Expansion on both ends of this seating to the dead ball line is quite feasable, more than doubling the seating.
The east side of the field has no present seating except bum on grass. The grass rises about 10 feet from the edge of the track to the row of trees shown on Google map. At the cost of about 30 pine trees another set of stands could be erected to duplicate/exceed the west side seating. Probably would have to move the lighting as well.
If you want to drive there on your own and you have a GPS set the destination to 200 College St E Guelph. I will be going over in the new year to see if any changes have occurred.
