Four rides, five thorns

It's been absolutely brutal lately. Getting sick of the thorns, I switched to a Conti Ultra Gatorskin I had sitting around this morning. 2 miles into my ride, yep, another thorn. It's never been this bad for me before; normally, I get one or two flats a year.

I might be picking up Armadillos this afternoon in an attempt to complete a ride.

Anyone else experiencing this?

Yep. Stupid goat heads are out in full force down here. An exceptionally bad year.
What's causing it? Global warming? Karma? Pete??

Just this week our Tues group ride had three flats and the Wed group ride had five flats. Two riders had double flats

I feel your pain. I rode over 500 miles with no flats while on vacation in Washington and Oregon.
Today, sticker flat. I fixed it, then in less than half a mile I had a glass shard flat.
Earlier this week I had a glass flat on my commuter bike.

I am, though, getting reasonably competent at changing tubes and patching tubes.

I'm surprised the Gatorskins didn't even help. I've found those to be just this side of bulletproof. In fact, one bike I built up with Gatorskins two or three years ago is still on its original tubes. Maybe try doubling up the protection with some Mr. Tuffy strips or slime tubes?

Gawd, won't the 80s ever die?

I've had bad luck with Contis in the past-the poor run continues. I was thinking something like Mr. Tuffy if I don't see an improvement. Did get me out of the habit of replacing tubes every time there's a problem. I now patch.

Man, I don't believe you went for it ... but if anyone would, you would.

One of my tubes has a very slow leak (goes completely flat over the course of ~5 days). I know, I need to replace it...but does anyone have any ideas what could cause that? I can't find the source of the leak.

Thorn resistant tubes = combined 9000 miles of flat free rides and still going.

Have you tried immersing the tube in a bucket of water?

+1 - a small hole near the valve perhaps?

Is there any way to change thread titles? Went out to the garage just now and noticed another flat.

You might dig through the tire and look for thorns. One person on today's ride had 4 flats as a result of thorns from a previous ride. She's going to just replace the tires. Can't find all the little buggers.

Speak of the Devil, yesterday I was talking to a guy at work who's just getting back on his 30 yo 12 spd. Complained about thorns and flats. I told him "Just get some modern tires, they're impervious to thorns." I haven't had a thorn flat in more than 20 years.

Hmmm, I had immersed the tube in water before but not the valve itself...guess I will try that when I have a moment between trips. Thanks for the suggestion.

Slime. With it you just pull the goat heads out and let the slime do its job of plugging the holes. I buy generic tubes and add the slime myself. To get it into a tube with a presta valve you can just cut into the tire, squirt the slime in, and then patch it up.

Just got back from leading my son's boy scout troop on rides around Bass Lake and Yosemite. Not a single flat, fortunately.

Looks like it's just local. Thanks for all the suggestions.

Specific to the valve, you should wiggle it (the valve stem) around because there are times it won't leak in one position, but will in another, so you should look at the base carefully, especially if it's an old tube.

Last Tuesday two flats in 5 miles. One was a goathead, other probably was too.
