I have never been, but since it is the weekend of my birthday I may just be able to con someone into making the 5 hour drive with me, plus I might have some birthday money.
Is it all just frags, or would there be colonies as well? I have seen plenty of colonies there. Crazy4Coral's for instance, trailer was full of them last time I was in their trailer at Brantford, although this is their first time at London. Big Show normally has nice size mini colonies and colonies.
Does it tend to be all really high end stuff or is there a good selection of frags under $20 too? $5-$500 prices and coral for just about any budget
Do the vendors charge tax? Normally included in the posted price, but that is up to the individual vendor how they list their items.
Are they typically willing to make deals if you buy multiple corals? Again, up to the vendor and what you purchase, however yes, normally the more you buy the better the deals
If you show up after the 'crazy' part is over is there still a good selection usually? Normally there is a good selection through out the entire show. Some vendors bring extra and fill their tanks as the day progresses. If you see something you like, do not pass on it as there is a good chance it will not be there when you come back though.
Sorry, many questions but I need you to convince me the long drive is worth it!
