It may be worth it, especially in May. In April, on a pleasant unseasonably warm day, started early in the morning, both the trees on the south and west perimeter of the sports field "the bowl" may show early warbler arrivals. I saw my first Canada warbler there but missed the Kentucky warbler.
The tiny marsh often reveals something of interest despite its diminutive dimensions, pulling way beyond its weight class, and the two spits are a must ... Pipit Point pointing east and West Point deserves a salute. At the end of May the spits might host various shorebirds, most often Semipalmated sandpiper, Dunlin, and Ruddy Turnstone. You might witness a flock flying either east or west just off the shoreline because they may settle down at the tip of one spit and then collectively decide to visit the opposite spit, right at the tip. When I see a flock I just station myself just off the tip of one end and wait. If they land on the boulders near me, then I gradually move one boulder closer while ignoring them and staring out onto the lake. After a minute I'll move closer by another boulder, and so forth. When I'm close enough for my shortsighted gear then I gradually turn toward them with the camera over my face and swing my lens into position ... shorebirds bearing (whatever), range 10 meters ... release the shutter. Geez, I almost typed torpedo. Ignoring birds while closing the distance does not always work but not looking directly at them, as if uninterested never fails to improve a photographers success.
Also, climbing down to the marina side lets you get closer to water-level while keeping the sun at your back and the marina host all kinds of water fowl. I captured a shot of my first Red-necked grebe there while using just a point-and-shoot camera. I can still remember it well. I laid down on the ground facing the marina bay and two grebe saw me, then swam directly toward me, closing the range from quite a distance until I felt alarmed that their intent was ramming me, red alert, red alert. What was I worried about ... I'm on land! My imagination gets hold of me and anything can happen. Anyway, both grebe belayed their full speed approach just 15 meters away from shore and then shuffled back-and-forth checking me out. I've had that happen while within a blind, but never while fully exposed. That experience got me hooked on Sam Smith, but back then I took transit from Scarborough ... a long haul.
