If you are going to Connaught, definitely bring something to cover your gear *between* relays, especially when you are down range at the 700 & 800 meter lines. At a minimum some heavy trash bags if you are packing everything, or a tarp and some bungee if you are carting your stuff.
I found there is a particular size of plastic tote that nests just about perfectly in a Tipke cart. Plus it makes loading/unloading the gear at the start & finish of each day *way*. easier.
Look up a local burger joint called "The Works"... awesome ala carte burgers - and you can get your poutine fix there too
