My mother in laws place is near Highland Creek and the Rouge. It is just such an exercise even by myself to get to Sunnyside that in the end it is not worth the time and effort. Easier to ride there or the Don.I took my son and his friend out to Sunnyside last month, thinking it was going to be a hit. I have to say, with all due respect to the good intentions behind the project, the siting is a bit of a challenge. I knew going in that it would be a wee bit noisy sandwiched between 12 odd lanes of traffic, but what I wasn't prepared for was getting across lakeshore and then the cross-street from the parking lot with two 8 year-olds on their bikes. we were stranded for a number of minutes on that tiny pedestrian island half way through the crossing, and with the kids being their usual antsy selves it was distinctly dicey. Then to make matters slightly worse, both kids took one look at it and declared joyride was better. It didn't matter to them that it was a beautiful late spring day and no time to be inside (although i couldn't help noticing a comparative lack of shade on the site and immediately worrying about whether i put on enough sunblock). So we promptly packed up and drove out to markham. I can't speak to designs of the big jump lines, but as for the pump track which is all my son can ride anyway, the one down on the flats is significantly better. Not to mention the shade, relative quiet, and a great user vibe. Can't help thinking a more entrepreneurial municipality would have found a way to make the flats site work.
