LOL Bill yes you would!
I was bitten by a good size red back spider (think black widow but more venomous) on the foot last year at a BBQ. Quite painful as you say Jeff. Although on the upside I just sat with my foot in the esky all night so a beer was never far away!
The real problem for me though is a type of native wasp local to my area. I've been bitten by them a number of times and although very painful more so than the spider bites I've had didn't think to much of it and kept working in the garden. Fast forward 20 minute and this is me, on the resus table. Doc's said I made it to the ER with 3 or 4 minutes to spare before my throat closed completely...
Note the shirt that happened to be the first one my wife got for me that day
As it happens our local native paper wasps have a cumulative venom that never totally leaves your system. If you've been stung a couple of times in the last year or so it just keeps adding up. Little buggers hey.
